    LCM for 63 and 84

    "Least Common Multiple" Calculator

    Least Common Multiple of

    and

    What's the Least Common Multiple (LCM) of 63 and 84?

    Answer

    LCM of 63 and 84 is
    252

    (Two hundred fifty-two)

    Finding LCM for 63 and 84 using GCF of these numbers

    The first method to find LCM for numbers 63 and 84 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 63 and 84 is 21, so

    LCM = (63 × 84) ÷ 21

    LCM = 5292 ÷ 21

    LCM = 252

    Finding LCM for 63 and 84 by Listing Multiples

    The second method to find LCM for numbers 63 and 84 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

    Multiples of 84: 84, 168, 252, 336, 420

    So the LCM for 63 and 84 is 252

    Finding LCM for 63 and 84 by Prime Factorization

    Another method to find LCM for numbers 63 and 84 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 84: 2, 2, 3, 7 (exponent form: 22, 31, 71)

    32 × 71 × 22 = 252
