Answer

LCM of 25 and 15 is 75

(Seventy-five)

Finding LCM for 25 and 15 using GCF of these numbers

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

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 25 and 15 is 5, so

LCM = (25 × 15) ÷ 5

LCM = 375 ÷ 5

LCM = 75

Finding LCM for 25 and 15 by Listing Multiples

The second method to find LCM for numbers 25 and 15 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 25: 25, 50, 75, 100, 125

Multiples of 15: 15, 30, 45, 60, 75, 90, 105

So the LCM for 25 and 15 is 75

Finding LCM for 25 and 15 by Prime Factorization

Another method to find LCM for numbers 25 and 15 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 25: 5, 5 (exponent form: 52)

All Prime Factors of 15: 3, 5 (exponent form: 31, 51)

52 × 31 = 75
