The LCM is 36,288
It is: 4
The least common multiple is the product of the two numbers divided by their greatest common factor. Their greatest common factor is 8, so the least common multiple is 56 x 64 ÷ 8 = 448.
The least common multiple of 56 , 64 = 448
The Least Common Multiple (LCM) of (16,28,64) is 448
The LCM is: 448
The GCF is 4.
Yes - 448/8 = 56
Answer: Infinity or there is none. One common multiple of 8 and 28 is 224. If I double it, which is 448, I have a larger common multiple. If I double it again, which is 896, I have an even larger common multiple. I can continue doubling it forever, so there is no greatest common multiple, or it can be said to be infinite.
