LCM for 25 and 180
What's the Least Common Multiple (LCM) of 25 and 180?
(Nine hundred)
Finding LCM for 25 and 180 using GCF's of these numbers
The first method to find LCM for numbers 25 and 180 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 25 and 180 is 5, so
LCM = (25 × 180) ÷ 5
LCM = 4500 ÷ 5
LCM = 900
