What's the Least Common Multiple (LCM) of 100 and 220?

Answer

LCM of 100 and 220 is 1,100

(One thousand, one hundred)

Finding LCM for 100 and 220 using GCF of these numbers

The first method to find LCM for numbers 100 and 220 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 100 and 220 is 20, so

LCM = (100 × 220) ÷ 20

LCM = 22000 ÷ 20

LCM = 1100

Finding LCM for 100 and 220 by Listing Multiples

The second method to find LCM for numbers 100 and 220 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 100: 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300

Multiples of 220: 220, 440, 660, 880, 1100, 1320, 1540

So the LCM for 100 and 220 is 1100

Finding LCM for 100 and 220 by Prime Factorization

Another method to find LCM for numbers 100 and 220 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 100: 2, 2, 5, 5 (exponent form: 22, 52)

All Prime Factors of 220: 2, 2, 5, 11 (exponent form: 22, 51, 111)

22 × 52 × 111 = 1100
