What's the Least Common Multiple (LCM) of 33 and 43?

Answer

LCM of 33 and 43 is 1,419

(One thousand, four hundred nineteen)

Finding LCM for 33 and 43 using GCF of these numbers

The first method to find LCM for numbers 33 and 43 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 33 and 43 is 1, so

LCM = (33 × 43) ÷ 1

LCM = 1419 ÷ 1

LCM = 1419

Finding LCM for 33 and 43 by Listing Multiples

The second method to find LCM for numbers 33 and 43 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 33: 33, 66, 99, 132, 165, 198, 231, 264, 297, 330, 363, 396, 429, 462, 495, 528, 561, 594, 627, 660, 693, 726, 759, 792, 825, 858, 891, 924, 957, 990, 1023, 1056, 1089, 1122, 1155, 1188, 1221, 1254, 1287, 1320, 1353, 1386, 1419, 1452, 1485

Multiples of 43: 43, 86, 129, 172, 215, 258, 301, 344, 387, 430, 473, 516, 559, 602, 645, 688, 731, 774, 817, 860, 903, 946, 989, 1032, 1075, 1118, 1161, 1204, 1247, 1290, 1333, 1376, 1419, 1462, 1505

So the LCM for 33 and 43 is 1419

Finding LCM for 33 and 43 by Prime Factorization

Another method to find LCM for numbers 33 and 43 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 33: 3, 11 (exponent form: 31, 111)

All Prime Factors of 43: 43 (exponent form: 431)

31 × 111 × 431 = 1419
