Answer: 60

Work Shown

LCM = (x*y)/GCF

LCM = (12*5)/1

LCM = 60

The formula applies when dealing with two numbers only.

We can check this by listing out the multiples of each.

  • 12, 24, 36, 48, 60, 72, 84, ...
  • 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, ...

The number 60 shows up as the first common multiple of both lists.
