LCM for 7 and 36
What's the Least Common Multiple (LCM) of 7 and 36?
(Two hundred fifty-two)
Finding LCM for 7 and 36 using GCF's of these numbers
The first method to find LCM for numbers 7 and 36 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 7 and 36 is 1, so
LCM = (7 × 36) ÷ 1
LCM = 252 ÷ 1
LCM = 252
