    LCM for 34 and 38

    "Least Common Multiple" Calculator

    Least Common Multiple of

    and

    What's the Least Common Multiple (LCM) of 34 and 38?

    Answer

    LCM of 34 and 38 is
    646

    (Six hundred forty-six)

    Finding LCM for 34 and 38 using GCF of these numbers

    The first method to find LCM for numbers 34 and 38 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 34 and 38 is 2, so

    LCM = (34 × 38) ÷ 2

    LCM = 1292 ÷ 2

    LCM = 646

    Finding LCM for 34 and 38 by Listing Multiples

    The second method to find LCM for numbers 34 and 38 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 34: 34, 68, 102, 136, 170, 204, 238, 272, 306, 340, 374, 408, 442, 476, 510, 544, 578, 612, 646, 680, 714

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

    So the LCM for 34 and 38 is 646

    Finding LCM for 34 and 38 by Prime Factorization

    Another method to find LCM for numbers 34 and 38 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 34: 2, 17 (exponent form: 21, 171)

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

    21 × 171 × 191 = 646
