LCM for 45 and 95
What's the Least Common Multiple (LCM) of 45 and 95?
(Eight hundred fifty-five)
Finding LCM for 45 and 95 using GCF's of these numbers
The first method to find LCM for numbers 45 and 95 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 45 and 95 is 5, so
LCM = (45 × 95) ÷ 5
LCM = 4275 ÷ 5
LCM = 855
