5,2,2
The prime factorization of 20 is: 2 × 2 × 5
Prime factorization of 20 in exponential form is: 22x5
The prime factorization of 20 is 5x2x2 or 5 x 2^2 20=2^2*5
Prime Factorization:20 = 2 * 2 * 530 = 2 * 3 * 5
20/2=10/2=5 5*2*2 equals prime factorization of 20.
It is 2*2*5 = 20
The prime factorization for 12 is 2 x 2 x 3The prime factorization for 20 is 2 x 2 x 5GCF of (12,20) = 4
2*2*5 = 20
20 = 22 x 51
20 = 22 x 51
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 12 is: 2 X 2 X 3 The prime factorization of 18 is: 2 X 3 X 3 The prime factorization of 20 is: 2 X 2 X 5
