What's the Least Common Multiple (LCM) of 42 and 44?

Answer

LCM of 42 and 44 is
924

(Nine hundred twenty-four)

Finding LCM for 42 and 44 using GCF of these numbers

The first method to find LCM for numbers 42 and 44 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 42 and 44 is 2, so

LCM = (42 × 44) ÷ 2

LCM = 1848 ÷ 2

LCM = 924

Finding LCM for 42 and 44 by Listing Multiples

The second method to find LCM for numbers 42 and 44 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 42: 42, 84, 126, 168, 210, 252, 294, 336, 378, 420, 462, 504, 546, 588, 630, 672, 714, 756, 798, 840, 882, 924, 966, 1008

Multiples of 44: 44, 88, 132, 176, 220, 264, 308, 352, 396, 440, 484, 528, 572, 616, 660, 704, 748, 792, 836, 880, 924, 968, 1012

So the LCM for 42 and 44 is 924

Finding LCM for 42 and 44 by Prime Factorization

Another method to find LCM for numbers 42 and 44 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 42: 2, 3, 7 (exponent form: 21, 31, 71)

All Prime Factors of 44: 2, 2, 11 (exponent form: 22, 111)

22 × 31 × 71 × 111 = 924
