    LCM for 38 and 42

    "Least Common Multiple" Calculator

    Least Common Multiple of

    and

    What's the Least Common Multiple (LCM) of 38 and 42?

    Answer

    LCM of 38 and 42 is
    798

    (Seven hundred ninety-eight)

    Finding LCM for 38 and 42 using GCF of these numbers

    The first method to find LCM for numbers 38 and 42 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 38 and 42 is 2, so

    LCM = (38 × 42) ÷ 2

    LCM = 1596 ÷ 2

    LCM = 798

    Finding LCM for 38 and 42 by Listing Multiples

    The second method to find LCM for numbers 38 and 42 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 38: 38, 76, 114, 152, 190, 228, 266, 304, 342, 380, 418, 456, 494, 532, 570, 608, 646, 684, 722, 760, 798, 836, 874

    Multiples of 42: 42, 84, 126, 168, 210, 252, 294, 336, 378, 420, 462, 504, 546, 588, 630, 672, 714, 756, 798, 840, 882

    So the LCM for 38 and 42 is 798

    Finding LCM for 38 and 42 by Prime Factorization

    Another method to find LCM for numbers 38 and 42 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 38: 2, 19 (exponent form: 21, 191)

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

    21 × 191 × 31 × 71 = 798
