What's the Least Common Multiple (LCM) of 21 and 59?

Answer

LCM of 21 and 59 is 1,239

(One thousand, two hundred thirty-nine)

Finding LCM for 21 and 59 using GCF of these numbers

The first method to find LCM for numbers 21 and 59 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 21 and 59 is 1, so

LCM = (21 × 59) ÷ 1

LCM = 1239 ÷ 1

LCM = 1239

Finding LCM for 21 and 59 by Listing Multiples

The second method to find LCM for numbers 21 and 59 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 21: 21, 42, 63, 84, 105, 126, 147, 168, 189, 210, 231, 252, 273, 294, 315, 336, 357, 378, 399, 420, 441, 462, 483, 504, 525, 546, 567, 588, 609, 630, 651, 672, 693, 714, 735, 756, 777, 798, 819, 840, 861, 882, 903, 924, 945, 966, 987, 1008, 1029, 1050, 1071, 1092, 1113, 1134, 1155, 1176, 1197, 1218, 1239, 1260, 1281

Multiples of 59: 59, 118, 177, 236, 295, 354, 413, 472, 531, 590, 649, 708, 767, 826, 885, 944, 1003, 1062, 1121, 1180, 1239, 1298, 1357

So the LCM for 21 and 59 is 1239

Finding LCM for 21 and 59 by Prime Factorization

Another method to find LCM for numbers 21 and 59 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 21: 3, 7 (exponent form: 31, 71)

All Prime Factors of 59: 59 (exponent form: 591)

31 × 71 × 591 = 1239
