What's the Least Common Multiple (LCM) of 12 and 39?

Answer

LCM of 12 and 39 is 156

(One hundred fifty-six)

Finding LCM for 12 and 39 using GCF of these numbers

The first method to find LCM for numbers 12 and 39 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 12 and 39 is 3, so

LCM = (12 × 39) ÷ 3

LCM = 468 ÷ 3

LCM = 156

Finding LCM for 12 and 39 by Listing Multiples

The second method to find LCM for numbers 12 and 39 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180

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

So the LCM for 12 and 39 is 156

Finding LCM for 12 and 39 by Prime Factorization

Another method to find LCM for numbers 12 and 39 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 12: 2, 2, 3 (exponent form: 22, 31)

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

22 × 31 × 131 = 156
