What's the Least Common Multiple (LCM) of 16 and 84?

Answer: LCM of 16 and 84 is 336

(Three hundred thirty-six)

Finding LCM for 16 and 84 using GCF's of these numbers

The first method to find LCM for numbers 16 and 84 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 16 and 84 is 4, so

LCM = (16 × 84) ÷ 4

LCM = 1344 ÷ 4

LCM = 336
