What's the Least Common Multiple (LCM) of 49 and 100?

Answer

LCM of 49 and 100 is
4,900

(Four thousand nine hundred)

Finding LCM for 49 and 100 using GCF of these numbers

The first method to find LCM for numbers 49 and 100 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 49 and 100 is 1, so

LCM = (49 × 100) ÷ 1

LCM = 4,900 ÷ 1

LCM = 4,900
