    What's the Least Common Multiple (LCM) of 40 and 63?

    Answer

    LCM of 40 and 63 is
    2,520

    (Two thousand five hundred twenty)

    Finding LCM for 40 and 63 using GCF of these numbers

    The first method to find LCM for numbers 40 and 63 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 40 and 63 is 1, so

    LCM = (40 × 63) ÷ 1

    LCM = 2,520 ÷ 1

    LCM = 2,520

    Finding LCM for 40 and 63 by Listing Multiples

    The second method to find LCM for numbers 40 and 63 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, 1,360, 1,400, 1,440, 1,480, 1,520, 1,560, 1,600, 1,640, 1,680, 1,720, 1,760, 1,800, 1,840, 1,880, 1,920, 1,960, 2,000, 2,040, 2,080, 2,120, 2,160, 2,200, 2,240, 2,280, 2,320, 2,360, 2,400, 2,440, 2,480, 2,520, 2,560, 2,600

    Multiples of 63: 63, 126, 189, 252, 315, 378, 441, 504, 567, 630, 693, 756, 819, 882, 945, 1,008, 1,071, 1,134, 1,197, 1,260, 1,323, 1,386, 1,449, 1,512, 1,575, 1,638, 1,701, 1,764, 1,827, 1,890, 1,953, 2,016, 2,079, 2,142, 2,205, 2,268, 2,331, 2,394, 2,457, 2,520, 2,583, 2,646

    So the LCM for 40 and 63 is 2,520

    Finding LCM for 40 and 63 by Prime Factorization

    Another method to find LCM for numbers 40 and 63 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 63: 3, 3, 7 (exponent form: 32, 71)

    23 × 51 × 32 × 71 = 2,520
