What's the Least Common Multiple (LCM) of 56 and 64?

Answer: LCM of 56 and 64 is 448

(Four hundred forty-eight)

Finding LCM for 56 and 64 using GCF's of these numbers

The first method to find LCM for numbers 56 and 64 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 56 and 64 is 8, so

LCM = (56 × 64) ÷ 8

LCM = 3584 ÷ 8

LCM = 448

Finding LCM for 56 and 64 by Listing Multiples

The second method to find LCM for numbers 56 and 64 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 56: 56, 112, 168, 224, 280, 336, 392, 448, 504, 560

Multiples of 64: 64, 128, 192, 256, 320, 384, 448, 512, 576

So the LCM for 56 and 64 is 448

Finding LCM for 56 and 64 by Prime Factorization

Another method to find LCM for numbers 56 and 64 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 56: 2, 2, 2, 7 (exponent form: 23, 71)

All Prime Factors of 64: 2, 2, 2, 2, 2, 2 (exponent form: 26)

26 × 71 = 448
