What's the Least Common Multiple (LCM) of 63 and 77?

Answer

LCM of 63 and 77 is
693

(Six hundred ninety-three)

Finding LCM for 63 and 77 using GCF of these numbers

The first method to find LCM for numbers 63 and 77 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 63 and 77 is 7, so

LCM = (63 × 77) ÷ 7

LCM = 4,851 ÷ 7

LCM = 693

Finding LCM for 63 and 77 by Listing Multiples

The second method to find LCM for numbers 63 and 77 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, 756, 819

Multiples of 77: 77, 154, 231, 308, 385, 462, 539, 616, 693, 770, 847

So the LCM for 63 and 77 is 693

Finding LCM for 63 and 77 by Prime Factorization

Another method to find LCM for numbers 63 and 77 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 77: 7, 11 (exponent form: 71, 111)

32 × 71 × 111 = 693
