What's the Least Common Multiple (LCM) of 33 and 40?

Answer

LCM of 33 and 40 is 1,320

(One thousand, three hundred twenty)

Finding LCM for 33 and 40 using GCF of these numbers

The first method to find LCM for numbers 33 and 40 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 33 and 40 is 1, so

LCM = (33 × 40) ÷ 1

LCM = 1320 ÷ 1

LCM = 1320

Finding LCM for 33 and 40 by Listing Multiples

The second method to find LCM for numbers 33 and 40 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

Multiples of 40: 40, 80, 120, 160, 200, 240, 280, 320, 360, 400, 440, 480, 520, 560, 600, 640, 680, 720, 760, 800, 840, 880, 920, 960, 1000, 1040, 1080, 1120, 1160, 1200, 1240, 1280, 1320, 1360, 1400

So the LCM for 33 and 40 is 1320

Finding LCM for 33 and 40 by Prime Factorization

Another method to find LCM for numbers 33 and 40 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 40: 2, 2, 2, 5 (exponent form: 23, 51)

31 × 111 × 23 × 51 = 1320
