    and

    What's the Least Common Multiple (LCM) of 16 and 40?

    Answer

    LCM of 16 and 40 is
    80

    (Eighty)

    Finding LCM for 16 and 40 using GCF of these numbers

    The first method to find LCM for numbers 16 and 40 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 16 and 40 is 8, so

    LCM = (16 × 40) ÷ 8

    LCM = 640 ÷ 8

    LCM = 80

    Finding LCM for 16 and 40 by Listing Multiples

    The second method to find LCM for numbers 16 and 40 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 16: 16, 32, 48, 64, 80, 96, 112

    Multiples of 40: 40, 80, 120, 160

    So the LCM for 16 and 40 is 80

    Finding LCM for 16 and 40 by Prime Factorization

    Another method to find LCM for numbers 16 and 40 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 16: 2, 2, 2, 2 (exponent form: 24)

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

    24 × 51 = 80
