What's the Least Common Multiple (LCM) of 64 and 84?

Answer

LCM of 64 and 84 is 1,344

(One thousand, three hundred forty-four)

Finding LCM for 64 and 84 using GCF of these numbers

The first method to find LCM for numbers 64 and 84 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 64 and 84 is 4, so

LCM = (64 × 84) ÷ 4

LCM = 5376 ÷ 4

LCM = 1344

Finding LCM for 64 and 84 by Listing Multiples

The second method to find LCM for numbers 64 and 84 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 64: 64, 128, 192, 256, 320, 384, 448, 512, 576, 640, 704, 768, 832, 896, 960, 1024, 1088, 1152, 1216, 1280, 1344, 1408, 1472

Multiples of 84: 84, 168, 252, 336, 420, 504, 588, 672, 756, 840, 924, 1008, 1092, 1176, 1260, 1344, 1428, 1512

So the LCM for 64 and 84 is 1344

Finding LCM for 64 and 84 by Prime Factorization

Another method to find LCM for numbers 64 and 84 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 64: 2, 2, 2, 2, 2, 2 (exponent form: 26)

All Prime Factors of 84: 2, 2, 3, 7 (exponent form: 22, 31, 71)

26 × 31 × 71 = 1344
