    What's the Least Common Multiple (LCM) of 72 and 84?

    Answer

    LCM of 72 and 84 is
    504

    (Five hundred four)

    Finding LCM for 72 and 84 using GCF of these numbers

    The first method to find LCM for numbers 72 and 84 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 72 and 84 is 12, so

    LCM = (72 × 84) ÷ 12

    LCM = 6,048 ÷ 12

    LCM = 504

    Finding LCM for 72 and 84 by Listing Multiples

    The second method to find LCM for numbers 72 and 84 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 72: 72, 144, 216, 288, 360, 432, 504, 576, 648

    Multiples of 84: 84, 168, 252, 336, 420, 504, 588, 672

    So the LCM for 72 and 84 is 504

    Finding LCM for 72 and 84 by Prime Factorization

    Another method to find LCM for numbers 72 and 84 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 72: 2, 2, 2, 3, 3 (exponent form: 23, 32)

    All Prime Factors of 84: 2, 2, 3, 7 (exponent form: 22, 31, 71)

    23 × 32 × 71 = 504
