Does 1 have a factor of 1?
Not Prime Factorization1 is not the prime factorization of 36. To find the prime factorization of 36, start with any two factors:2 X 18 = 36Then, continue to factor any number in the equation that can be factored:2 X 2 X 9 = 362 X 2 X 3 X 3 = 36When you can no longer factor any number in the equation, you have the prime factorization, so the prime factorization of 36 is 2 X 2 X 3 X 3.
