    What's the Least Common Multiple (LCM) of 63 and 42?

    Answer

    LCM of 63 and 42 is
    126

    (One hundred twenty-six)

    Finding LCM for 63 and 42 using GCF of these numbers

    The first method to find LCM for numbers 63 and 42 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 63 and 42 is 21, so

    LCM = (63 × 42) ÷ 21

    LCM = 2646 ÷ 21

    LCM = 126

    Finding LCM for 63 and 42 by Listing Multiples

    The second method to find LCM for numbers 63 and 42 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 63: 63, 126, 189, 252

    Multiples of 42: 42, 84, 126, 168, 210

    So the LCM for 63 and 42 is 126

    Finding LCM for 63 and 42 by Prime Factorization

    Another method to find LCM for numbers 63 and 42 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 63: 3, 3, 7 (exponent form: 32, 71)

    All Prime Factors of 42: 2, 3, 7 (exponent form: 21, 31, 71)

    32 × 71 × 21 = 126
