    LCM for 70 and 310

    "Least Common Multiple" Calculator

    Least Common Multiple of

    and

    What's the Least Common Multiple (LCM) of 70 and 310?

    Answer

    LCM of 70 and 310 is
    2,170

    (Two thousand one hundred seventy)

    Finding LCM for 70 and 310 using GCF of these numbers

    The first method to find LCM for numbers 70 and 310 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 70 and 310 is 10, so

    LCM = (70 × 310) ÷ 10

    LCM = 21700 ÷ 10

    LCM = 2170

    Finding LCM for 70 and 310 by Listing Multiples

    The second method to find LCM for numbers 70 and 310 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, 1050, 1120, 1190, 1260, 1330, 1400, 1470, 1540, 1610, 1680, 1750, 1820, 1890, 1960, 2030, 2100, 2170, 2240, 2310

    Multiples of 310: 310, 620, 930, 1240, 1550, 1860, 2170, 2480, 2790

    So the LCM for 70 and 310 is 2170

    Finding LCM for 70 and 310 by Prime Factorization

    Another method to find LCM for numbers 70 and 310 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 310: 2, 5, 31 (exponent form: 21, 51, 311)

    21 × 51 × 71 × 311 = 2170
