    What's the Least Common Multiple (LCM) of 70 and 400?

    Answer

    LCM of 70 and 400 is
    2,800

    (Two thousand eight hundred)

    Finding LCM for 70 and 400 using GCF of these numbers

    The first method to find LCM for numbers 70 and 400 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 70 and 400 is 10, so

    LCM = (70 × 400) ÷ 10

    LCM = 28,000 ÷ 10

    LCM = 2,800

    Finding LCM for 70 and 400 by Listing Multiples

    The second method to find LCM for numbers 70 and 400 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 70: 70, 140, 210, 280, 350, 420, 490, 560, 630, 700, 770, 840, 910, 980, 1,050, 1,120, 1,190, 1,260, 1,330, 1,400, 1,470, 1,540, 1,610, 1,680, 1,750, 1,820, 1,890, 1,960, 2,030, 2,100, 2,170, 2,240, 2,310, 2,380, 2,450, 2,520, 2,590, 2,660, 2,730, 2,800, 2,870, 2,940

    Multiples of 400: 400, 800, 1,200, 1,600, 2,000, 2,400, 2,800, 3,200, 3,600

    So the LCM for 70 and 400 is 2,800

    Finding LCM for 70 and 400 by Prime Factorization

    Another method to find LCM for numbers 70 and 400 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 70: 2, 5, 7 (exponent form: 21, 51, 71)

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

    24 × 52 × 71 = 2,800
