What's the Least Common Multiple (LCM) of 54 and 63?

Answer

LCM of 54 and 63 is
378

(Three hundred seventy-eight)

Finding LCM for 54 and 63 using GCF of these numbers

The first method to find LCM for numbers 54 and 63 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 54 and 63 is 9, so

LCM = (54 × 63) ÷ 9

LCM = 3,402 ÷ 9

LCM = 378

Finding LCM for 54 and 63 by Listing Multiples

The second method to find LCM for numbers 54 and 63 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 54: 54, 108, 162, 216, 270, 324, 378, 432, 486

Multiples of 63: 63, 126, 189, 252, 315, 378, 441, 504

So the LCM for 54 and 63 is 378

Finding LCM for 54 and 63 by Prime Factorization

Another method to find LCM for numbers 54 and 63 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 54: 2, 3, 3, 3 (exponent form: 21, 33)

All Prime Factors of 63: 3, 3, 7 (exponent form: 32, 71)

21 × 33 × 71 = 378
