    and

    What's the Least Common Multiple (LCM) of 40 and 320?

    Answer

    LCM of 40 and 320 is
    320

    (Three hundred twenty)

    Finding LCM for 40 and 320 using GCF of these numbers

    The first method to find LCM for numbers 40 and 320 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 40 and 320 is 40, so

    LCM = (40 × 320) ÷ 40

    LCM = 12800 ÷ 40

    LCM = 320

    Finding LCM for 40 and 320 by Listing Multiples

    The second method to find LCM for numbers 40 and 320 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 40: 40, 80, 120, 160, 200, 240, 280, 320, 360, 400

    Multiples of 320: 320, 640, 960

    So the LCM for 40 and 320 is 320

    Finding LCM for 40 and 320 by Prime Factorization

    Another method to find LCM for numbers 40 and 320 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 40: 2, 2, 2, 5 (exponent form: 23, 51)

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

    26 × 51 = 320
