### Is 1 the prime factorization of 36?

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

### What factors of 36 are not factors of 18?

To answer this question you first need to isolate the prime factors in each number. In this case the numbers are 36 and 18 so the prime factors are: 18 = 2x3x3 36 = 2x2x3x3 The next step is to identify any unique factors. In this case, the only prime factor 36 has which 18 doesn't is a second 2. Thus any combination of the prime factors of 36 which includes both 2s will not…
