LCM for 36 and 28
What's the Least Common Multiple (LCM) of 36 and 28?
(Two hundred fifty-two)
Finding LCM for 36 and 28 using GCF's of these numbers
The first method to find LCM for numbers 36 and 28 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 36 and 28 is 4, so
LCM = (36 × 28) ÷ 4
LCM = 1008 ÷ 4
LCM = 252
