    What's the Least Common Multiple (LCM) of 81 and 99?

    Answer

    LCM of 81 and 99 is
    891

    (Eight hundred ninety-one)

    Finding LCM for 81 and 99 using GCF of these numbers

    The first method to find LCM for numbers 81 and 99 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 81 and 99 is 9, so

    LCM = (81 × 99) ÷ 9

    LCM = 8,019 ÷ 9

    LCM = 891

    Finding LCM for 81 and 99 by Listing Multiples

    The second method to find LCM for numbers 81 and 99 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

    Multiples of 99: 99, 198, 297, 396, 495, 594, 693, 792, 891, 990, 1089

    So the LCM for 81 and 99 is 891

    Finding LCM for 81 and 99 by Prime Factorization

    Another method to find LCM for numbers 81 and 99 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 99: 3, 3, 11 (exponent form: 32, 111)

    34 × 111 = 891
