    What's the Least Common Multiple (LCM) of 18 and 66?

    Answer

    LCM of 18 and 66 is
    198

    (One hundred ninety-eight)

    Finding LCM for 18 and 66 using GCF of these numbers

    The first method to find LCM for numbers 18 and 66 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 18 and 66 is 6, so

    LCM = (18 × 66) ÷ 6

    LCM = 1,188 ÷ 6

    LCM = 198

    Finding LCM for 18 and 66 by Listing Multiples

    The second method to find LCM for numbers 18 and 66 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 18: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216, 234

    Multiples of 66: 66, 132, 198, 264, 330

    So the LCM for 18 and 66 is 198

    Finding LCM for 18 and 66 by Prime Factorization

    Another method to find LCM for numbers 18 and 66 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 18: 2, 3, 3 (exponent form: 21, 32)

    All Prime Factors of 66: 2, 3, 11 (exponent form: 21, 31, 111)

    21 × 32 × 111 = 198
