    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
