What's the Least Common Multiple (LCM) of 220 and 308?

Answer

LCM of 220 and 308 is
1,540

(One thousand five hundred forty)

Finding LCM for 220 and 308 using GCF of these numbers

The first method to find LCM for numbers 220 and 308 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 220 and 308 is 44, so

LCM = (220 × 308) ÷ 44

LCM = 67,760 ÷ 44

LCM = 1,540

Finding LCM for 220 and 308 by Listing Multiples

The second method to find LCM for numbers 220 and 308 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 220: 220, 440, 660, 880, 1,100, 1,320, 1,540, 1,760, 1,980

Multiples of 308: 308, 616, 924, 1,232, 1,540, 1,848, 2,156

So the LCM for 220 and 308 is 1,540

Finding LCM for 220 and 308 by Prime Factorization

Another method to find LCM for numbers 220 and 308 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

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

All Prime Factors of 308: 2, 2, 7, 11 (exponent form: 22, 71, 111)

22 × 51 × 111 × 71 = 1,540
