    Least Common Multiple of
    and

    What's the Least Common Multiple (LCM) of 42 and 1,365?

    Answer

    LCM of 42 and 1,365 is
    2,730

    (Two thousand seven hundred thirty)

    Finding LCM for 42 and 1,365 using GCF of these numbers

    The first method to find LCM for numbers 42 and 1,365 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 42 and 1,365 is 21, so

    LCM = (42 × 1,365) ÷ 21

    LCM = 57,330 ÷ 21

    LCM = 2,730

    Finding LCM for 42 and 1,365 by Listing Multiples

    The second method to find LCM for numbers 42 and 1,365 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 42: 42, 84, 126, 168, 210, 252, 294, 336, 378, 420, 462, 504, 546, 588, 630, 672, 714, 756, 798, 840, 882, 924, 966, 1,008, 1,050, 1,092, 1,134, 1,176, 1,218, 1,260, 1,302, 1,344, 1,386, 1,428, 1,470, 1,512, 1,554, 1,596, 1,638, 1,680, 1,722, 1,764, 1,806, 1,848, 1,890, 1,932, 1,974, 2,016, 2,058, 2,100, 2,142, 2,184, 2,226, 2,268, 2,310, 2,352, 2,394, 2,436, 2,478, 2,520, 2,562, 2,604, 2,646, 2,688, 2,730, 2,772, 2,814

    Multiples of 1,365: 1,365, 2,730, 4,095, 5,460

    So the LCM for 42 and 1,365 is 2,730

    Finding LCM for 42 and 1,365 by Prime Factorization

    Another method to find LCM for numbers 42 and 1,365 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 42: 2, 3, 7 (exponent form: 21, 31, 71)

    All Prime Factors of 1,365: 3, 5, 7, 13 (exponent form: 31, 51, 71, 131)

    21 × 31 × 71 × 51 × 131 = 2,730
