    What's the Least Common Multiple (LCM) of 80 and 405?

    Answer

    LCM of 80 and 405 is
    6,480

    (Six thousand four hundred eighty)

    Finding LCM for 80 and 405 using GCF of these numbers

    The first method to find LCM for numbers 80 and 405 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 80 and 405 is 5, so

    LCM = (80 × 405) ÷ 5

    LCM = 32,400 ÷ 5

    LCM = 6,480

    Finding LCM for 80 and 405 by Listing Multiples

    The second method to find LCM for numbers 80 and 405 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 80: 80, 160, 240, 320, 400, 480, 560, 640, 720, 800, 880, 960, 1,040, 1,120, 1,200, 1,280, 1,360, 1,440, 1,520, 1,600, 1,680, 1,760, 1,840, 1,920, 2,000, 2,080, 2,160, 2,240, 2,320, 2,400, 2,480, 2,560, 2,640, 2,720, 2,800, 2,880, 2,960, 3,040, 3,120, 3,200, 3,280, 3,360, 3,440, 3,520, 3,600, 3,680, 3,760, 3,840, 3,920, 4,000, 4,080, 4,160, 4,240, 4,320, 4,400, 4,480, 4,560, 4,640, 4,720, 4,800, 4,880, 4,960, 5,040, 5,120, 5,200, 5,280, 5,360, 5,440, 5,520, 5,600, 5,680, 5,760, 5,840, 5,920, 6,000, 6,080, 6,160, 6,240, 6,320, 6,400, 6,480, 6,560, 6,640

    Multiples of 405: 405, 810, 1,215, 1,620, 2,025, 2,430, 2,835, 3,240, 3,645, 4,050, 4,455, 4,860, 5,265, 5,670, 6,075, 6,480, 6,885, 7,290

    So the LCM for 80 and 405 is 6,480

    Finding LCM for 80 and 405 by Prime Factorization

    Another method to find LCM for numbers 80 and 405 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 80: 2, 2, 2, 2, 5 (exponent form: 24, 51)

    All Prime Factors of 405: 3, 3, 3, 3, 5 (exponent form: 34, 51)

    24 × 51 × 34 = 6,480
