What is the least common multiple of set of numbers? 3,10,12,8

  • Math -

    Start with the largest number -- 12

    12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180 . . .

    Which of the above numbers is evenly divisible by 3, 10, and 8?

  • Math -

    120

  • Math -

    3= 3
    10 = 2*5
    12 = 2*2*3
    8 = 2*2*2

    start with the longest string of prime factors : 2*2*2
    now add on any other factors from the other strings that have not yet been put down

    2*2*2*3*5 = 120
