## How to Calculate Prime Factors of 24?

Calculating the prime factors of 24 involves breaking down the number into the prime numbers that multiply together to result in 24. Prime factors are the building blocks of a number, consisting only of prime numbers, which are numbers greater than 1 that have no positive divisors other than 1 and themselves. Here’s how to find the prime factors of 24:

• Begin with 2, the smallest prime number. Check if 24 is divisible by 2. Since 24 is even, it is divisible by 2.

## Step 2: Divide the number by the smallest prime.

• Divide 24 by 2, which gives 12. So, 2 is a prime factor, and 24 can be written as 2 × 12.

## Step 3: Continue dividing by the smallest prime.

• Divide 12 by 2 again, resulting in 6. Now, 24 can be written as 2 × 2 × 6.

## Step 4: Repeat the process with the quotient.

• Divide 6 by 2, giving 3. Now, 24 can be written as 2 × 2 × 2 × 3.

## Step 5: Check if the quotient is a prime number.

• The quotient 3 is a prime number. Thus, the factorization process is complete.
