    and

    What's the Least Common Multiple (LCM) of 19 and 43?

    Answer

    LCM of 19 and 43 is
    817

    (Eight hundred seventeen)

    Finding LCM for 19 and 43 using GCF of these numbers

    The first method to find LCM for numbers 19 and 43 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 19 and 43 is 1, so

    LCM = (19 × 43) ÷ 1

    LCM = 817 ÷ 1

    LCM = 817

    Finding LCM for 19 and 43 by Listing Multiples

    The second method to find LCM for numbers 19 and 43 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 19: 19, 38, 57, 76, 95, 114, 133, 152, 171, 190, 209, 228, 247, 266, 285, 304, 323, 342, 361, 380, 399, 418, 437, 456, 475, 494, 513, 532, 551, 570, 589, 608, 627, 646, 665, 684, 703, 722, 741, 760, 779, 798, 817, 836, 855

    Multiples of 43: 43, 86, 129, 172, 215, 258, 301, 344, 387, 430, 473, 516, 559, 602, 645, 688, 731, 774, 817, 860, 903

    So the LCM for 19 and 43 is 817

    Finding LCM for 19 and 43 by Prime Factorization

    Another method to find LCM for numbers 19 and 43 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 19: 19 (exponent form: 191)

    All Prime Factors of 43: 43 (exponent form: 431)

    191 × 431 = 817
