What's the Least Common Multiple (LCM) of 8 and 43?

Answer

LCM of 8 and 43 is 344

(Three hundred forty-four)

Finding LCM for 8 and 43 using GCF of these numbers

The first method to find LCM for numbers 8 and 43 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 8 and 43 is 1, so

LCM = (8 × 43) ÷ 1

LCM = 344 ÷ 1

LCM = 344

Finding LCM for 8 and 43 by Listing Multiples

The second method to find LCM for numbers 8 and 43 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, 128, 136, 144, 152, 160, 168, 176, 184, 192, 200, 208, 216, 224, 232, 240, 248, 256, 264, 272, 280, 288, 296, 304, 312, 320, 328, 336, 344, 352, 360

Multiples of 43: 43, 86, 129, 172, 215, 258, 301, 344, 387, 430

So the LCM for 8 and 43 is 344

Finding LCM for 8 and 43 by Prime Factorization

Another method to find LCM for numbers 8 and 43 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 8: 2, 2, 2 (exponent form: 23)

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

23 × 431 = 344
