    What's the Least Common Multiple (LCM) of 8 and 4?

    Answer

    LCM of 8 and 4 is
    8

    (Eight)

    Finding LCM for 8 and 4 using GCF of these numbers

    The first method to find LCM for numbers 8 and 4 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 8 and 4 is 4, so

    LCM = (8 × 4) ÷ 4

    LCM = 32 ÷ 4

    LCM = 8

    Finding LCM for 8 and 4 by Listing Multiples

    The second method to find LCM for numbers 8 and 4 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 8: 8, 16, 24

    Multiples of 4: 4, 8, 12, 16

    So the LCM for 8 and 4 is 8

    Finding LCM for 8 and 4 by Prime Factorization

    Another method to find LCM for numbers 8 and 4 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 8: 2, 2, 2 (exponent form: 23)

    All Prime Factors of 4: 2, 2 (exponent form: 22)

    23 = 8
