What's the Least Common Multiple (LCM) of 25 and 100?

Answer: LCM of 25 and 100 is 100

(Hundred)

Finding LCM for 25 and 100 using GCF's of these numbers

The first method to find LCM for numbers 25 and 100 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 25 and 100 is 25, so

LCM = (25 × 100) ÷ 25

LCM = 2500 ÷ 25

LCM = 100

Finding LCM for 25 and 100 by Listing Multiples

The second method to find LCM for numbers 25 and 100 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 25: 25, 50, 75, 100, 125, 150

Multiples of 100: 100, 200, 300, 400, 500, 600, [...], 100

So the LCM for 25 and 100 is 100

Finding LCM for 25 and 100 by Prime Factorization

Another method to find LCM for numbers 25 and 100 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 100: 2, 2, 5, 5 (exponent form: 2², 5²)

5² × 2² = 100
