Explaining Prime Numbers

Before diving into the prime factorization of 75, it's important to understand what prime numbers are. Prime numbers are whole numbers greater than 1 that have no divisors other than 1 and themselves. For example, 2, 3, 5, 7, and 11 are all prime numbers.

The Factors of 75

To determine the prime factorization of 75, let's first list out all the factors of 75. Factors are the numbers that evenly divide a given number. For 75, the factors are 1, 3, 5, 15, 25, and 75.

Divisibility by 3

One way to find the prime factorization is by using divisibility rules. Since 75 is divisible by 3 (75 ÷ 3 = 25), we know that 3 is one of the prime factors.

Divisibility by 5

Another divisibility rule we can use is for the number 5. If a number ends in 0 or 5, it is divisible by 5. In the case of 75, it ends with 5, so we can divide it by 5 (75 ÷ 5 = 15). Therefore, we have found another prime factor: 5.

Prime Factorization of 75

Now that we have found the prime factors 3 and 5, we can express the prime factorization of 75 as the product of these primes: 3 × 5.

The Unique Representation

Prime factorization is a fundamental concept in mathematics that involves breaking down a number into its prime factors. This process allows us to express a given number as a product of its prime factors, which are the building blocks of natural numbers. By understanding prime factorization, we can gain insights into the unique composition of a number and explore its mathematical properties.

Definition of prime numbers: A brief explanation of prime numbers.

Before delving into prime factorization, it is essential to grasp the concept of prime numbers. Prime numbers are positive integers greater than 1 that are divisible only by 1 and themselves. They cannot be divided evenly by any other number. For example, 2, 3, 5, 7, and 11 are prime numbers because they have no divisors other than 1 and themselves.

Calculation of factors: Demonstrating how factors are calculated for a given number.

To understand prime factorization, we must first comprehend factors. Factors are the numbers that divide evenly into a given number without leaving a remainder. For instance, the factors of 12 are 1, 2, 3, 4, 6, and 12 because they divide 12 without a remainder. Calculating factors involves finding all the numbers that divide into a given number.

Prime factorization of 75: Identifying the prime factors of the number 75.

Now, let's focus on the prime factorization of 75. To determine the prime factors of 75, we need to find the prime numbers that divide evenly into it.

Breaking down into prime factors:

The step-by-step process of finding the prime factors of 75 involves dividing the number by the smallest prime number and continuing this process until we obtain only prime factors.

First, we divide 75 by the smallest prime number, which is 2. However, 75 is not divisible by 2, so we move on to the next prime number, which is 3.

When we divide 75 by 3, we get 25 as the quotient. So, we have found one prime factor: 3.

Next, we continue dividing the quotient, which is 25, by prime numbers to identify additional prime factors. We try dividing by 2, but once again, it does not divide evenly. Moving on to the next prime number, 3, we find that 25 is divisible by 5.

Therefore, the prime factorization of 75 is 3 × 5 × 5 (or 3 × 5²).

Divisibility by prime numbers:

Understanding the divisibility of a number by prime numbers is crucial in prime factorization. By determining which prime numbers divide evenly into a given number, we can identify its prime factors.

In the case of 75, we found that it is divisible by the prime numbers 3 and 5. These two prime numbers are the building blocks of 75's prime factorization.

Factors of 75:

Before exploring the prime factorization of 75 further, let's list all the factors of 75. This preliminary step helps us identify the potential prime factors.

The factors of 75 are 1, 3, 5, 15, 25, and 75.

Finding the prime factors:

Now that we have identified the potential prime factors using the factors of 75, we can determine which ones are indeed prime. In this case, both 3 and 5 are prime numbers.

By multiplying these prime factors together, we obtain the original number, 75. Thus, the prime factorization of 75 is 3 × 5 × 5 (or 3 × 5²).

Multiplying prime factors:

When we multiply the prime factors of 75, we obtain the original number as a result. This multiplication process confirms the correctness of our prime factorization.

In this case, 3 × 5 × 5 equals 75, which verifies that we have correctly determined the prime factors of 75.

In mathematics, prime factorization refers to the process of breaking down a number into its prime factors. Prime factors are the prime numbers that divide a given number exactly without leaving any remainder.

Let's explore the prime factorization of 75 using an explanation voice and tone:

  1. Step 1: Finding the Divisible Prime Factors

    2. To begin the prime factorization of 75, we look for the smallest prime number that can divide 75 without leaving a remainder. The smallest prime number is 2, but it does not divide 75 evenly. The next prime number is 3, and it divides 75 without a remainder. Therefore, we can conclude that 3 is a prime factor of 75.

  2. Step 2: Dividing by the Found Prime Factor

    3. Now that we have found one prime factor, which is 3, we divide 75 by this prime factor. The quotient is 25.

  3. Step 3: Repeating the Process

    4. We repeat the process and continue to find prime factors for the quotient 25. We start with the smallest prime number again, which is 2. However, 2 does not divide 25 evenly. We move on to the next prime number, which is 3, and it also does not divide 25 evenly. Finally, we try 5, and it divides 25 without leaving a remainder. Thus, we can conclude that 5 is another prime factor of 75.

  4. Step 4: Continuing the Division

    5. Since we have found another prime factor, which is 5, we divide the current quotient 25 by this prime factor. The result is 5.

  5. Step 5: Finalizing the Prime Factorization

    6. Now, we have reached a point where the quotient, which is 5, cannot be divided any further using prime numbers. Therefore, we can say that 5 is the last prime factor of 75.

  6. Step 6: Writing the Prime Factorization

    7. To write the final prime factorization of 75, we combine all the prime factors we found: 3, 5, and 5. Therefore, 75 can be expressed as the product of its prime factors: 3 x 5 x 5.

In summary, the prime factorization of 75 is 3 x 5 x 5.
