What's the Least Common Multiple (LCM) of 64 and 121?

Answer

LCM of 64 and 121 is
7,744

(Seven thousand seven hundred forty-four)

Finding LCM for 64 and 121 using GCF of these numbers

The first method to find LCM for numbers 64 and 121 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 64 and 121 is 1, so

LCM = (64 × 121) ÷ 1

LCM = 7,744 ÷ 1

LCM = 7,744
