What's the Least Common Multiple (LCM) of 165 and 231?

Answer

LCM of 165 and 231 is
1,155

(One thousand one hundred fifty-five)

Finding LCM for 165 and 231 using GCF of these numbers

The first method to find LCM for numbers 165 and 231 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 165 and 231 is 33, so

LCM = (165 × 231) ÷ 33

LCM = 38,115 ÷ 33

LCM = 1,155

Finding LCM for 165 and 231 by Listing Multiples

The second method to find LCM for numbers 165 and 231 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 165: 165, 330, 495, 660, 825, 990, 1,155, 1,320, 1,485

Multiples of 231: 231, 462, 693, 924, 1,155, 1,386, 1,617

So the LCM for 165 and 231 is 1,155

Finding LCM for 165 and 231 by Prime Factorization

Another method to find LCM for numbers 165 and 231 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

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

All Prime Factors of 231: 3, 7, 11 (exponent form: 31, 71, 111)

31 × 51 × 111 × 71 = 1,155
