Insects have 6 legs, and spiders have 8 legs. What is the least number of insects and the least number of spiders possible so that each group has the same number of legs?

  1. Sam Winchester

    6 x 1 = 6 8 x 1 = 8
    6 x 2 = 12 8 x 2 = 16
    6 x 3 = 18 8 x 3 = 24
    6 x 4 = 24

    Therefore you need 3 spiders and 4 insects.

  2. Reiny

    The LCM, (Least Common Multiple) of 6 and 8 is 24
    so you need 24/6 or 4 insects and 24/8 or 3 spiders.
