    What's the Least Common Multiple (LCM) of 55 and 77?

    Answer

    LCM of 55 and 77 is
    385

    (Three hundred eighty-five)

    Finding LCM for 55 and 77 using GCF of these numbers

    The first method to find LCM for numbers 55 and 77 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 55 and 77 is 11, so

    LCM = (55 × 77) ÷ 11

    LCM = 4,235 ÷ 11

    LCM = 385

    Finding LCM for 55 and 77 by Listing Multiples

    The second method to find LCM for numbers 55 and 77 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 55: 55, 110, 165, 220, 275, 330, 385, 440, 495

    Multiples of 77: 77, 154, 231, 308, 385, 462, 539

    So the LCM for 55 and 77 is 385

    Finding LCM for 55 and 77 by Prime Factorization

    Another method to find LCM for numbers 55 and 77 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 55: 5, 11 (exponent form: 51, 111)

    All Prime Factors of 77: 7, 11 (exponent form: 71, 111)

    51 × 111 × 71 = 385
