What's the Least Common Multiple (LCM) of 63 and 81?

Answer

LCM of 63 and 81 is
567

(Five hundred sixty-seven)

Finding LCM for 63 and 81 using GCF of these numbers

The first method to find LCM for numbers 63 and 81 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 63 and 81 is 9, so

LCM = (63 × 81) ÷ 9

LCM = 5,103 ÷ 9

LCM = 567

Finding LCM for 63 and 81 by Listing Multiples

The second method to find LCM for numbers 63 and 81 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 63: 63, 126, 189, 252, 315, 378, 441, 504, 567, 630, 693

Multiples of 81: 81, 162, 243, 324, 405, 486, 567, 648, 729

So the LCM for 63 and 81 is 567

Finding LCM for 63 and 81 by Prime Factorization

Another method to find LCM for numbers 63 and 81 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

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

All Prime Factors of 81: 3, 3, 3, 3 (exponent form: 34)

34 × 71 = 567
