A prime factorization is the unique way to list any integer greater than 1 as a product of prime numbers. An example of the prime factorization of a composite number is 20=2*2*5 or 20=2^2*5. The prime factorization of a prime number is itself. e.g. 11=11.
The prime factorization of 20 is: 2 × 2 × 5
Prime Factorization:20 = 2 * 2 * 530 = 2 * 3 * 5
2*2*5 = 20
Breaking a number down into a multiplication of its prime numbers. For example 20 = 2 x 2 x 5
Let's do 20 first.20 can be written as 4x5. Note that 5 is prime but 4 is not. So write 4 as 2x2.The prime factorization of 20 is 2x2x5.Now for 60, we have 3x20.We can use what we just did and write the prime factorization of 60 as2x2x3x5.

The prime factorization of 20 is: 2 × 2 × 5
The prime factorization of 40 is 2 X 2 X 2 X 5 or 2^3 x 5. To find the prime factorization of 40, find the lowest prime factor that will divide into 40. That number is 2, and 2 X 20 equals 40. 2 is prime, so it is one of the factors. 20 is a composite number, so must be factored. The lowest prime number that will divide evenly into 20 is 2. 2 X 10 equals 20. Another 2 is in the prime factorization, so you have 2 X 2 X 10. Ten is not a prime number, so the factoring has to continue. 2 X 5 equals 10. both numbers are prime, so now all you have to do is write out the factorization.
The only even prime number is 2. It happens twice in the prime factorization of 20.
Prime factorization of 20 in exponential form is: 22x5

Prime Factorization:20 = 2 * 2 * 530 = 2 * 3 * 5
The prime factorization of 20 is 5x2x2 or 5 x 2^2 20=2^2*5
2 x 2 x 5
2*2*5 = 20
