    LCM for 23 and 57

    "Least Common Multiple" Calculator

    Least Common Multiple of

    and

    What's the Least Common Multiple (LCM) of 23 and 57?

    Answer

    LCM of 23 and 57 is
    1,311

    (One thousand three hundred eleven)

    Finding LCM for 23 and 57 using GCF of these numbers

    The first method to find LCM for numbers 23 and 57 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 23 and 57 is 1, so

    LCM = (23 × 57) ÷ 1

    LCM = 1311 ÷ 1

    LCM = 1311

    Finding LCM for 23 and 57 by Listing Multiples

    The second method to find LCM for numbers 23 and 57 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 23: 23, 46, 69, 92, 115, 138, 161, 184, 207, 230, 253, 276, 299, 322, 345, 368, 391, 414, 437, 460, 483, 506, 529, 552, 575, 598, 621, 644, 667, 690, 713, 736, 759, 782, 805, 828, 851, 874, 897, 920, 943, 966, 989, 1012, 1035, 1058, 1081, 1104, 1127, 1150, 1173, 1196, 1219, 1242, 1265, 1288, 1311, 1334, 1357

    Multiples of 57: 57, 114, 171, 228, 285, 342, 399, 456, 513, 570, 627, 684, 741, 798, 855, 912, 969, 1026, 1083, 1140, 1197, 1254, 1311, 1368, 1425

    So the LCM for 23 and 57 is 1311

    Finding LCM for 23 and 57 by Prime Factorization

    Another method to find LCM for numbers 23 and 57 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 23: 23 (exponent form: 231)

    All Prime Factors of 57: 3, 19 (exponent form: 31, 191)

    231 × 31 × 191 = 1311
