To write prime numbers in multiplication form, you simply list them as factors multiplied together. For example, the prime factorization of 12 is 2 x 2 x 3, as 2 and 3 are prime numbers. Likewise, the prime factorization of 20 is 2 x 2 x 5.
The prime factorization of 20 is: 2 × 2 × 5
20 10,2 5,2,2
Prime Factorization:20 = 2 * 2 * 530 = 2 * 3 * 5
2*2*5 = 20
20 10,2 5,2,2 2 x 2 x 5 = 20
80 / \ 40 2 / \ 20 2 / \ 10 2 / \ 5 2 24*5
Use a factor tree. 20 10,2 5,2,2
