What's the Least Common Multiple (LCM) of 39 and 57?

Answer

LCM of 39 and 57 is 741

(Seven hundred forty-one)

Finding LCM for 39 and 57 using GCF of these numbers

The first method to find LCM for numbers 39 and 57 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 39 and 57 is 3, so

LCM = (39 × 57) ÷ 3

LCM = 2223 ÷ 3

LCM = 741

Finding LCM for 39 and 57 by Listing Multiples

The second method to find LCM for numbers 39 and 57 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, 312, 351, 390, 429, 468, 507, 546, 585, 624, 663, 702, 741, 780, 819

Multiples of 57: 57, 114, 171, 228, 285, 342, 399, 456, 513, 570, 627, 684, 741, 798, 855

So the LCM for 39 and 57 is 741

Finding LCM for 39 and 57 by Prime Factorization

Another method to find LCM for numbers 39 and 57 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 57: 3, 19 (exponent form: 31, 191)

31 × 131 × 191 = 741
