What's the Least Common Multiple (LCM) of 121 and 165?

Answer

LCM of 121 and 165 is
1,815

(One thousand eight hundred fifteen)

Finding LCM for 121 and 165 using GCF of these numbers

The first method to find LCM for numbers 121 and 165 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 121 and 165 is 11, so

LCM = (121 × 165) ÷ 11

LCM = 19,965 ÷ 11

LCM = 1,815

Finding LCM for 121 and 165 by Listing Multiples

The second method to find LCM for numbers 121 and 165 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 121: 121, 242, 363, 484, 605, 726, 847, 968, 1,089, 1,210, 1,331, 1,452, 1,573, 1,694, 1,815, 1,936, 2,057

Multiples of 165: 165, 330, 495, 660, 825, 990, 1,155, 1,320, 1,485, 1,650, 1,815, 1,980, 2,145

So the LCM for 121 and 165 is 1,815

Finding LCM for 121 and 165 by Prime Factorization

Another method to find LCM for numbers 121 and 165 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 121: 11, 11 (exponent form: 112)

All Prime Factors of 165: 3, 5, 11 (exponent form: 31, 51, 111)

112 × 31 × 51 = 1,815
