What's the Least Common Multiple (LCM) of 42 and 162?

Answer: LCM of 42 and 162 is 1,134

(One thousand, one hundred thirty-four)

Finding LCM for 42 and 162 using GCF's of these numbers

The first method to find LCM for numbers 42 and 162 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 42 and 162 is 6, so

LCM = (42 × 162) ÷ 6

LCM = 6804 ÷ 6

LCM = 1134
