    2x - 4

    5x - 10

    factor both

    2 (x - 2)

    5 (x - 2)

    List all factors once

    (5) (2) (x-2)

    10x - 20

    Step-by-step explanation:

    First, factor both polynomials.

    2x - 4 = 2 (x - 2)

    5x - 10 = 5 (x - 2)

    The LCM is the product of the common and not common factors with larger exponent.

    LCM = 2 * 5 * (x - 2)

    LCM = 10 (x - 2) = 10x - 20
