    What's the Least Common Multiple (LCM) of 105 and 189?

    Answer

    LCM of 105 and 189 is
    945

    (Nine hundred forty-five)

    Finding LCM for 105 and 189 using GCF of these numbers

    The first method to find LCM for numbers 105 and 189 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 105 and 189 is 21, so

    LCM = (105 × 189) ÷ 21

    LCM = 19,845 ÷ 21

    LCM = 945

    Finding LCM for 105 and 189 by Listing Multiples

    The second method to find LCM for numbers 105 and 189 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 105: 105, 210, 315, 420, 525, 630, 735, 840, 945, 1050, 1155

    Multiples of 189: 189, 378, 567, 756, 945, 1134, 1323

    So the LCM for 105 and 189 is 945

    Finding LCM for 105 and 189 by Prime Factorization

    Another method to find LCM for numbers 105 and 189 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 105: 3, 5, 7 (exponent form: 31, 51, 71)

    All Prime Factors of 189: 3, 3, 3, 7 (exponent form: 33, 71)

    33 × 51 × 71 = 945
