What's the Least Common Multiple (LCM) of 16 and 56?

Answer: LCM of 16 and 56 is 112

(One hundred twelve)

Finding LCM for 16 and 56 using GCF's of these numbers

The first method to find LCM for numbers 16 and 56 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 16 and 56 is 8, so

LCM = (16 × 56) ÷ 8

LCM = 896 ÷ 8

LCM = 112
