    and

    What's the Least Common Multiple (LCM) of 40 and 155?

    Answer

    LCM of 40 and 155 is
    1,240

    (One thousand two hundred forty)

    Finding LCM for 40 and 155 using GCF of these numbers

    The first method to find LCM for numbers 40 and 155 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 40 and 155 is 5, so

    LCM = (40 × 155) ÷ 5

    LCM = 6,200 ÷ 5

    LCM = 1,240

    Finding LCM for 40 and 155 by Listing Multiples

    The second method to find LCM for numbers 40 and 155 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, 440, 480, 520, 560, 600, 640, 680, 720, 760, 800, 840, 880, 920, 960, 1,000, 1,040, 1,080, 1,120, 1,160, 1,200, 1,240, 1,280, 1,320

    Multiples of 155: 155, 310, 465, 620, 775, 930, 1,085, 1,240, 1,395, 1,550

    So the LCM for 40 and 155 is 1,240

    Finding LCM for 40 and 155 by Prime Factorization

    Another method to find LCM for numbers 40 and 155 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 155: 5, 31 (exponent form: 51, 311)

    23 × 51 × 311 = 1,240
