    What's the Least Common Multiple (LCM) of 72 and 80?

    Answer

    LCM of 72 and 80 is
    720

    (Seven hundred twenty)

    Finding LCM for 72 and 80 using GCF of these numbers

    The first method to find LCM for numbers 72 and 80 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 72 and 80 is 8, so

    LCM = (72 × 80) ÷ 8

    LCM = 5,760 ÷ 8

    LCM = 720

    Finding LCM for 72 and 80 by Listing Multiples

    The second method to find LCM for numbers 72 and 80 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, 720, 792, 864

    Multiples of 80: 80, 160, 240, 320, 400, 480, 560, 640, 720, 800, 880

    So the LCM for 72 and 80 is 720

    Finding LCM for 72 and 80 by Prime Factorization

    Another method to find LCM for numbers 72 and 80 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 80: 2, 2, 2, 2, 5 (exponent form: 24, 51)

    24 × 32 × 51 = 720
