LCM for 25 and 55

What's the Least Common Multiple (LCM) of 25 and 55?

Answer: LCM of 25 and 55 is 275

(Two hundred seventy-five)

Finding LCM for 25 and 55 using GCF's of these numbers

The first method to find LCM for numbers 25 and 55 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 25 and 55 is 5, so

LCM = (25 × 55) ÷ 5

LCM = 1375 ÷ 5

LCM = 275

Finding LCM for 25 and 55 by Listing Multiples

The second method to find LCM for numbers 25 and 55 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, 175, 200, 225, 250, 275, 300, 325

Multiples of 55: 55, 110, 165, 220, 275, 330, 385

So the LCM for 25 and 55 is 275

Finding LCM for 25 and 55 by Prime Factorization

Another method to find LCM for numbers 25 and 55 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 55: 5, 11 (exponent form: 51, 111)

52 × 111 = 275
