What's the Least Common Multiple (LCM) of 25 and 105?

Answer: LCM of 25 and 105 is 525

(Five hundred twenty-five)

Finding LCM for 25 and 105 using GCF's of these numbers

The first method to find LCM for numbers 25 and 105 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 25 and 105 is 5, so

LCM = (25 × 105) ÷ 5

LCM = 2625 ÷ 5

LCM = 525
