What's the Least Common Multiple (LCM) of 39 and 65?

Answer

LCM of 39 and 65 is
195

(One hundred ninety-five)

Finding LCM for 39 and 65 using GCF of these numbers

The first method to find LCM for numbers 39 and 65 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 39 and 65 is 13, so

LCM = (39 × 65) ÷ 13

LCM = 2,535 ÷ 13

LCM = 195

Finding LCM for 39 and 65 by Listing Multiples

The second method to find LCM for numbers 39 and 65 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 39: 39, 78, 117, 156, 195, 234, 273

Multiples of 65: 65, 130, 195, 260, 325

So the LCM for 39 and 65 is 195

Finding LCM for 39 and 65 by Prime Factorization

Another method to find LCM for numbers 39 and 65 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 39: 3, 13 (exponent form: 31, 131)

All Prime Factors of 65: 5, 13 (exponent form: 51, 131)

31 × 131 × 51 = 195
