What's the Least Common Multiple (LCM) of 49 and 63?

Answer

LCM of 49 and 63 is
441

(Four hundred forty-one)

Finding LCM for 49 and 63 using GCF of these numbers

The first method to find LCM for numbers 49 and 63 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 49 and 63 is 7, so

LCM = (49 × 63) ÷ 7

LCM = 3,087 ÷ 7

LCM = 441

Finding LCM for 49 and 63 by Listing Multiples

The second method to find LCM for numbers 49 and 63 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 49: 49, 98, 147, 196, 245, 294, 343, 392, 441, 490, 539

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

So the LCM for 49 and 63 is 441

Finding LCM for 49 and 63 by Prime Factorization

Another method to find LCM for numbers 49 and 63 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 49: 7, 7 (exponent form: 72)

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

72 × 32 = 441
