The GCF is 64.

The GCF is 56.

The GCF is 56.

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 GCF is 8.

448

8

As a product of its prime factors in exponents: 26*7 = 448

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.

The LCM is 448.

When calculating the LCM of two numbers, you first need to split them into their prime factors. In this case we get: 174 = 2x3x29 448 = 2x2x2x2x2x2x7 The next step is to identify any common factors. In this case both numbers have 2 as a common prime factor, so we can cross off the duplicate. That leaves 2, 2, 2, 2, 2, 2, 3, 7 and 29. Multiplying these together gives 38,976. Therefore the LCM of 174 and 448 is 38,976
