    and

    What's the Least Common Multiple (LCM) of 81 and 49?

    Answer

    LCM of 81 and 49 is
    3,969

    (Three thousand nine hundred sixty-nine)

    Finding LCM for 81 and 49 using GCF of these numbers

    The first method to find LCM for numbers 81 and 49 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 81 and 49 is 1, so

    LCM = (81 × 49) ÷ 1

    LCM = 3969 ÷ 1

    LCM = 3969

    Finding LCM for 81 and 49 by Listing Multiples

    The second method to find LCM for numbers 81 and 49 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 81: 81, 162, 243, 324, 405, 486, 567, 648, 729, 810, 891, 972, 1053, 1134, 1215, 1296, 1377, 1458, 1539, 1620, 1701, 1782, 1863, 1944, 2025, 2106, 2187, 2268, 2349, 2430, 2511, 2592, 2673, 2754, 2835, 2916, 2997, 3078, 3159, 3240, 3321, 3402, 3483, 3564, 3645, 3726, 3807, 3888, 3969, 4050, 4131

    Multiples of 49: 49, 98, 147, 196, 245, 294, 343, 392, 441, 490, 539, 588, 637, 686, 735, 784, 833, 882, 931, 980, 1029, 1078, 1127, 1176, 1225, 1274, 1323, 1372, 1421, 1470, 1519, 1568, 1617, 1666, 1715, 1764, 1813, 1862, 1911, 1960, 2009, 2058, 2107, 2156, 2205, 2254, 2303, 2352, 2401, 2450, 2499, 2548, 2597, 2646, 2695, 2744, 2793, 2842, 2891, 2940, 2989, 3038, 3087, 3136, 3185, 3234, 3283, 3332, 3381, 3430, 3479, 3528, 3577, 3626, 3675, 3724, 3773, 3822, 3871, 3920, 3969, 4018, 4067

    So the LCM for 81 and 49 is 3969

    Finding LCM for 81 and 49 by Prime Factorization

    Another method to find LCM for numbers 81 and 49 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 81: 3, 3, 3, 3 (exponent form: 34)

    All Prime Factors of 49: 7, 7 (exponent form: 72)

    34 × 72 = 3969
