Find the least common multiple (LCM) for each of the following groups of numbers

12, 20, and 35

  • Math -

    That would be the number that contains the prime factors of all of the three numbers, for the maximum number of times that they appear in any single number.
    12 = 3*2*2
    20 = 2*2*5
    35 = 5*7

    The LCM is 2*2*3*5*7= 420
