    LCM for 20 and 165

    "Least Common Multiple" Calculator

    Least Common Multiple of

    and

    What's the Least Common Multiple (LCM) of 20 and 165?

    Answer

    LCM of 20 and 165 is
    660

    (Six hundred sixty)

    Finding LCM for 20 and 165 using GCF of these numbers

    The first method to find LCM for numbers 20 and 165 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 20 and 165 is 5, so

    LCM = (20 × 165) ÷ 5

    LCM = 3300 ÷ 5

    LCM = 660

    Finding LCM for 20 and 165 by Listing Multiples

    The second method to find LCM for numbers 20 and 165 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 20: 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, 320, 340, 360, 380, 400, 420, 440, 460, 480, 500, 520, 540, 560, 580, 600, 620, 640, 660, 680, 700

    Multiples of 165: 165, 330, 495, 660, 825, 990

    So the LCM for 20 and 165 is 660

    Finding LCM for 20 and 165 by Prime Factorization

    Another method to find LCM for numbers 20 and 165 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 20: 2, 2, 5 (exponent form: 22, 51)

    All Prime Factors of 165: 3, 5, 11 (exponent form: 31, 51, 111)

    22 × 51 × 31 × 111 = 660
