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. Th (MORE)
