The GCF is the factor, the LCM is the other one.
The product of the GCF and the LCM of two numbers is equal to the product of the original two numbers. Multiply the GCF and the LCM. The original two numbers will be another factor pair of that total. Find the factor pair that has that GCF and LCM.
The LCM of 16 and 64 is 64. Since 16 is a factor of 64, 64 is automatically the LCM of the pair.
factor pair = 1512,1 factor pair = 756,2 factor pair = 504,3 factor pair = 378,4 factor pair = 252,6 factor pair = 216,7 factor pair = 189,8 factor pair = 168,9 factor pair = 126,12 factor pair = 108,14 factor pair = 84,18 factor pair = 72,21 factor pair = 63,24 factor pair = 56,27 factor pair = 54,28 factor pair = 42,36
The LCM of 30 and 50 is 150.

factor pair = 650,1 factor pair = 325,2 factor pair = 130,5 factor pair = 65,10 factor pair = 50,13 factor pair = 26,25
factor pair = 36,1 factor pair = 18,2 factor pair = 12,3 factor pair = 9,4 factor pair = 6,6
factor pair = 90,1 factor pair = 45,2 factor pair = 30,3 factor pair = 18,5 factor pair = 15,6 factor pair = 10,9 Doctor Chuck Mathdoc
The set of (90,90) has a GCF and an LCM of 90.The set of (-90,-90) has a GCF and an LCM of 90.
Because it is a square and the factor pair of 8 and 8 is only listed as one factor.
3 2 x 3 x 7 = 42 Since 42 is a multiple of 3, it is automatically the LCM of the pair.
