What's the Least Common Multiple (LCM) of 27 and 40?

Answer

LCM of 27 and 40 is 1,080

(One thousand, eighty)

Finding LCM for 27 and 40 using GCF of these numbers

The first method to find LCM for numbers 27 and 40 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 27 and 40 is 1, so

LCM = (27 × 40) ÷ 1

LCM = 1080 ÷ 1

LCM = 1080

Finding LCM for 27 and 40 by Listing Multiples

The second method to find LCM for numbers 27 and 40 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 27: 27, 54, 81, 108, 135, 162, 189, 216, 243, 270, 297, 324, 351, 378, 405, 432, 459, 486, 513, 540, 567, 594, 621, 648, 675, 702, 729, 756, 783, 810, 837, 864, 891, 918, 945, 972, 999, 1026, 1053, 1080, 1107, 1134

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

So the LCM for 27 and 40 is 1080

Finding LCM for 27 and 40 by Prime Factorization

Another method to find LCM for numbers 27 and 40 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 27: 3, 3, 3 (exponent form: 33)

All Prime Factors of 40: 2, 2, 2, 5 (exponent form: 23, 51)

33 × 23 × 51 = 1080
