If the GCF of two numbers is 12 and the LCM is 24, the two numbers are 12 and 24.
The GCF is 12. The LCM is 24.
24 and 36
The numbers could be 4 and 24 or 8 and 12.
LCM(12, 18, 24) = 72; GCF(12, 18, 24) = 6.
24 and 48 have a GCF of 24 and an LCM of 48.
12 and 8
GCF: 4 LCM: 24
4 and 24, respectively.
72 and 12, respectively.
2 x 12 = 24, but there's an easier way if you remember that the product of the GCF and LCM of a pair of numbers will always be equal to the product of the two numbers.
2 and 24 satisfy that request. So do 6 and 8.
20 and 24
