What's the Least Common Multiple (LCM) of 105 and 165?

Answer

LCM of 105 and 165 is
1,155

(One thousand one hundred fifty-five)

Finding LCM for 105 and 165 using GCF of these numbers

The first method to find LCM for numbers 105 and 165 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 105 and 165 is 15, so

LCM = (105 × 165) ÷ 15

LCM = 17,325 ÷ 15

LCM = 1,155

Finding LCM for 105 and 165 by Listing Multiples

The second method to find LCM for numbers 105 and 165 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 105: 105, 210, 315, 420, 525, 630, 735, 840, 945, 1050, 1155, 1260, 1365

Multiples of 165: 165, 330, 495, 660, 825, 990, 1155, 1320, 1485

So the LCM for 105 and 165 is 1,155

Finding LCM for 105 and 165 by Prime Factorization

Another method to find LCM for numbers 105 and 165 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 105: 3, 5, 7 (exponent form: 31, 51, 71)

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

31 × 51 × 71 × 111 = 1,155
