    "Least Common Multiple" Calculator

    Least Common Multiple of

    and

    What's the Least Common Multiple (LCM) of 7 and 13?

    Answer

    LCM of 7 and 13 is
    91

    (Ninety-one)

    Finding LCM for 7 and 13 using GCF of these numbers

    The first method to find LCM for numbers 7 and 13 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 7 and 13 is 1, so

    LCM = (7 × 13) ÷ 1

    LCM = 91 ÷ 1

    LCM = 91

    Finding LCM for 7 and 13 by Listing Multiples

    The second method to find LCM for numbers 7 and 13 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105

    Multiples of 13: 13, 26, 39, 52, 65, 78, 91, 104, 117

    So the LCM for 7 and 13 is 91

    Finding LCM for 7 and 13 by Prime Factorization

    Another method to find LCM for numbers 7 and 13 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 7: 7 (exponent form: 71)

    All Prime Factors of 13: 13 (exponent form: 131)

    71 × 131 = 91
