    and

    What's the Least Common Multiple (LCM) of 320 and 640?

    Answer

    LCM of 320 and 640 is
    640

    (Six hundred forty)

    Finding LCM for 320 and 640 using GCF of these numbers

    The first method to find LCM for numbers 320 and 640 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 320 and 640 is 320, so

    LCM = (320 × 640) ÷ 320

    LCM = 204,800 ÷ 320

    LCM = 640

    Finding LCM for 320 and 640 by Listing Multiples

    The second method to find LCM for numbers 320 and 640 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 320: 320, 640, 960, 1,280

    Multiples of 640: 640, 1,280, 1,920

    So the LCM for 320 and 640 is 640

    Finding LCM for 320 and 640 by Prime Factorization

    Another method to find LCM for numbers 320 and 640 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 320: 2, 2, 2, 2, 2, 2, 5 (exponent form: 26, 51)

    All Prime Factors of 640: 2, 2, 2, 2, 2, 2, 2, 5 (exponent form: 27, 51)

    27 × 51 = 640
