What's the Least Common Multiple (LCM) of 31 and 32?

Answer

LCM of 31 and 32 is 992

(Nine hundred ninety-two)

Finding LCM for 31 and 32 using GCF of these numbers

The first method to find LCM for numbers 31 and 32 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 31 and 32 is 1, so

LCM = (31 × 32) ÷ 1

LCM = 992 ÷ 1

LCM = 992

Finding LCM for 31 and 32 by Listing Multiples

The second method to find LCM for numbers 31 and 32 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 31: 31, 62, 93, 124, 155, 186, 217, 248, 279, 310, 341, 372, 403, 434, 465, 496, 527, 558, 589, 620, 651, 682, 713, 744, 775, 806, 837, 868, 899, 930, 961, 992, 1023, 1054

Multiples of 32: 32, 64, 96, 128, 160, 192, 224, 256, 288, 320, 352, 384, 416, 448, 480, 512, 544, 576, 608, 640, 672, 704, 736, 768, 800, 832, 864, 896, 928, 960, 992, 1024, 1056

So the LCM for 31 and 32 is 992

Finding LCM for 31 and 32 by Prime Factorization

Another method to find LCM for numbers 31 and 32 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 31: 31 (exponent form: 311)

All Prime Factors of 32: 2, 2, 2, 2, 2 (exponent form: 25)

311 × 25 = 992
