What's the Least Common Multiple (LCM) of 120 and 220?

Answer: LCM of 120 and 220 is 1,320

(One thousand, three hundred twenty)

Finding LCM for 120 and 220 using GCF's of these numbers

The first method to find LCM for numbers 120 and 220 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 120 and 220 is 20, so

LCM = (120 × 220) ÷ 20

LCM = 26400 ÷ 20

LCM = 1320

Finding LCM for 120 and 220 by Listing Multiples

The second method to find LCM for numbers 120 and 220 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 120: 120, 240, 360, 480, 600, 720, 840, 960, 1080, 1200, 1320, 1440, 1560

Multiples of 220: 220, 440, 660, 880, 1100, 1320, 1540, 1760

So the LCM for 120 and 220 is 1320

Finding LCM for 120 and 220 by Prime Factorization

Another method to find LCM for numbers 120 and 220 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 120: 2, 2, 2, 3, 5 (exponent form: 23, 31, 51)

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

23 × 31 × 51 × 111 = 1320
