    What's the Least Common Multiple (LCM) of 80 and 120?

    Answer

    LCM of 80 and 120 is
    240

    (Two hundred forty)

    Finding LCM for 80 and 120 using GCF of these numbers

    The first method to find LCM for numbers 80 and 120 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 80 and 120 is 40, so

    LCM = (80 × 120) ÷ 40

    LCM = 9600 ÷ 40

    LCM = 240

    Finding LCM for 80 and 120 by Listing Multiples

    The second method to find LCM for numbers 80 and 120 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 80: 80, 160, 240, 320, 400

    Multiples of 120: 120, 240, 360, 480

    So the LCM for 80 and 120 is 240

    Finding LCM for 80 and 120 by Prime Factorization

    Another method to find LCM for numbers 80 and 120 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 80: 2, 2, 2, 2, 5 (exponent form: 24, 51)

    All Prime Factors of 120: 2, 2, 2, 3, 5 (exponent form: 23, 31, 51)

    24 × 51 × 31 = 240
