    "Least Common Multiple" Calculator

    Least Common Multiple of

    and

    What's the Least Common Multiple (LCM) of 7 and 18?

    Answer

    LCM of 7 and 18 is
    126

    (One hundred twenty-six)

    Finding LCM for 7 and 18 using GCF of these numbers

    The first method to find LCM for numbers 7 and 18 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 7 and 18 is 1, so

    LCM = (7 × 18) ÷ 1

    LCM = 126 ÷ 1

    LCM = 126

    Finding LCM for 7 and 18 by Listing Multiples

    The second method to find LCM for numbers 7 and 18 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, 112, 119, 126, 133, 140

    Multiples of 18: 18, 36, 54, 72, 90, 108, 126, 144, 162

    So the LCM for 7 and 18 is 126

    Finding LCM for 7 and 18 by Prime Factorization

    Another method to find LCM for numbers 7 and 18 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 18: 2, 3, 3 (exponent form: 21, 32)

    71 × 21 × 32 = 126
