The two numbers 18 and 27.
Factorising the lcm and gcf gives:
54 = 2 × 3³
9 = 3²
There must be 3² in both numbers, but there must be a 3³ and a 2 which must appear in the prime factorisations of the two numbers. Putting a 2 with one 3² and a 3 with the other 3² leads to the two numbers:
2 × 3² = 18
3 × 3³ = 3³ = 27
as the two smallest numbers with gcf=9 and lcm=54. The other distribution of both 2 and 3 with one 3² results in the two number 3² = 9 and 2 × 3³ = 54, the latter of which is larger than both the 18 and 27 previously found.

What numbers have gcf of 12 and LCM of 144?
The greatest common factor (GCF) of two numbers is the largest number that divides both numbers evenly. In this case, the GCF of 12 and 144 is 12. The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both numbers. The LCM of 12 and 144 is 144. Therefore, the numbers that have a GCF of 12 and an LCM of 144 are 12 and 144.

What are the 2 smallest numbers whose GCF is 9 and whose LCM is 54?
18 and 9 * * * * * Not so. LCM(9, 18) = 18, not 54. The correct answer is 18, 27.
What are two numbers whose GCF is 20 and whose LCM is 100?
20 and 100.GCF is 20, and LCM is 100.
What is the pair of numbers whose gcf is 1 and LCM is 36?
The pair of numbers whose GCF is 1 and LCM is 36 is 9 and 4. The numbers should be greater than their GCF and less than their LCM.
When do you use GCF and LCM?
Gcf you use when you are finding the greatest factor for the numbers. Lcm you use when you are finding the smallest multiple in the numbers factors

Why are GCF and LCM are Almost always never equal?
Because the GCF is the largest factor common to all the numbers in the sample. The LCM is the smallest number that all the sample numbers will divide into !
