What's the Least Common Multiple (LCM) of 84 and 112?

Answer

LCM of 84 and 112 is
336

(Three hundred thirty-six)

Finding LCM for 84 and 112 using GCF of these numbers

The first method to find LCM for numbers 84 and 112 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 84 and 112 is 28, so

LCM = (84 × 112) ÷ 28

LCM = 9,408 ÷ 28

LCM = 336

Finding LCM for 84 and 112 by Listing Multiples

The second method to find LCM for numbers 84 and 112 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 84: 84, 168, 252, 336, 420, 504

Multiples of 112: 112, 224, 336, 448, 560

So the LCM for 84 and 112 is 336

Finding LCM for 84 and 112 by Prime Factorization

Another method to find LCM for numbers 84 and 112 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

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

All Prime Factors of 112: 2, 2, 2, 2, 7 (exponent form: 24, 71)

24 × 31 × 71 = 336
