LCM for 32 and 120
What's the Least Common Multiple (LCM) of 32 and 120?
(Four hundred eighty)
Finding LCM for 32 and 120 using GCF's of these numbers
The first method to find LCM for numbers 32 and 120 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 32 and 120 is 8, so
LCM = (32 × 120) ÷ 8
LCM = 3840 ÷ 8
LCM = 480
