LCM for 18 and 234
What's the Least Common Multiple (LCM) of 18 and 234?
(Two hundred thirty-four)
Finding LCM for 18 and 234 using GCF's of these numbers
The first method to find LCM for numbers 18 and 234 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 18 and 234 is 18, so
LCM = (18 × 234) ÷ 18
LCM = 4212 ÷ 18
LCM = 234
