    What's the Least Common Multiple (LCM) of 400 and 1,080?

    Answer

    LCM of 400 and 1,080 is
    10,800

    (Ten thousand eight hundred)

    Finding LCM for 400 and 1,080 using GCF of these numbers

    The first method to find LCM for numbers 400 and 1,080 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 400 and 1,080 is 40, so

    LCM = (400 × 1,080) ÷ 40

    LCM = 432,000 ÷ 40

    LCM = 10,800

    Finding LCM for 400 and 1,080 by Listing Multiples

    The second method to find LCM for numbers 400 and 1,080 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 400: 400, 800, 1,200, 1,600, 2,000, 2,400, 2,800, 3,200, 3,600, 4,000, 4,400, 4,800, 5,200, 5,600, 6,000, 6,400, 6,800, 7,200, 7,600, 8,000, 8,400, 8,800, 9,200, 9,600, 10,000, 10,400, 10,800, 11,200, 11,600

    Multiples of 1,080: 1,080, 2,160, 3,240, 4,320, 5,400, 6,480, 7,560, 8,640, 9,720, 10,800, 11,880, 12,960

    So the LCM for 400 and 1,080 is 10,800

    Finding LCM for 400 and 1,080 by Prime Factorization

    Another method to find LCM for numbers 400 and 1,080 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 400: 2, 2, 2, 2, 5, 5 (exponent form: 24, 52)

    All Prime Factors of 1,080: 2, 2, 2, 3, 3, 3, 5 (exponent form: 23, 33, 51)

    24 × 52 × 33 = 10,800
