What is the gcf and LCM of 12 and 27?
Express the numbers in prime factorisation in power form: 12 = 22 x 31 27 = 33 For gcf multiply together the lowest power of the common primes: gcf of 12 and 27 = 31 = 3 For LCM multiply together the highest power of all the primes (across the numbers): LCM of 12 and 27 = 22 x 33 = 108

How do you find the two smallest numbers who have a gcf of 9 and a LCM of 54?
LCM/GCF = 54/9 = 6 So you require two factors of 6 such that their maximum is the smallest. Therefore, rather than 1 and 6, you select 2 and 3. The two numbers are GCF*2 and GCF*3, that is 18 and 27.
