What's the Least Common Multiple (LCM) of 56 and 57?

Answer

LCM of 56 and 57 is
3,192

(Three thousand one hundred ninety-two)

Finding LCM for 56 and 57 using GCF of these numbers

The first method to find LCM for numbers 56 and 57 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 56 and 57 is 1, so

LCM = (56 × 57) ÷ 1

LCM = 3,192 ÷ 1

LCM = 3,192
