Answer: LCM of 15 and 25 is 75

(Seventy-five)

Finding LCM for 15 and 25 using GCF's of these numbers

The first method to find LCM for numbers 15 and 25 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 15 and 25 is 5, so

LCM = (15 × 25) ÷ 5

LCM = 375 ÷ 5

LCM = 75
