What's the Least Common Multiple (LCM) of 29 and 31?

Answer

LCM of 29 and 31 is 899

(Eight hundred ninety-nine)

Finding LCM for 29 and 31 using GCF of these numbers

The first method to find LCM for numbers 29 and 31 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 29 and 31 is 1, so

LCM = (29 × 31) ÷ 1

LCM = 899 ÷ 1

LCM = 899

Finding LCM for 29 and 31 by Listing Multiples

The second method to find LCM for numbers 29 and 31 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 29: 29, 58, 87, 116, 145, 174, 203, 232, 261, 290, 319, 348, 377, 406, 435, 464, 493, 522, 551, 580, 609, 638, 667, 696, 725, 754, 783, 812, 841, 870, 899, 928, 957

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

So the LCM for 29 and 31 is 899

Finding LCM for 29 and 31 by Prime Factorization

Another method to find LCM for numbers 29 and 31 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 29: 29 (exponent form: 291)

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

291 × 311 = 899
