LCM for 12 and 162
What's the Least Common Multiple (LCM) of 12 and 162?
(Three hundred twenty-four)
Finding LCM for 12 and 162 using GCF's of these numbers
The first method to find LCM for numbers 12 and 162 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 12 and 162 is 6, so
LCM = (12 × 162) ÷ 6
LCM = 1944 ÷ 6
LCM = 324
