Prime factorisation of 18 = 2*3*3
Prime factorisation of 30 = 2*3*5
Then 1/18 = 5*1/5*18 = 5*90 (using the prime factor of 30 that is not in 18)
and 1/30 = 3*1/3*30 = 3*90 (using the extra prime factor of 18 that is not in 30)
So 1/18 + 1/30 = 5/90 + 3/90 = 8/90 = 4/45
1 is not a prime number, so it wouldn't be present in any prime factorization. Prime numbers don't really have factorizations, that is, the factorization is the number itself. There are prime numbers greater than 100.
117 = 3 × 3 × 13245 = 5 × 7 × 7

When reducing a fraction, find the GCF of the numerator and denominator and divide them both by it. If the GCF is 1, the fraction is already in its simplest form.
36/77 is already in simplest form, since the greatest common factor of 36 and 77 is 1. The prime factorization of 36 is 2*2*3*3 The prime factorization of 77 is 7*11
it is easier to find the prime factorization because you do not have to keep multiplying over and over and over again!!!!
Prime factorization refers to whole numbers, not fractions. 100/50 = 2, which is already prime and therefore has no prime factorization other than itself.

5 x 5 x 7 x 7 = 1225 5 x 7 x 7 = 245 1225/245 = 5 The prime factorization of 5 is 5.
