Question

Sam and Carlos are bowling with plastic pins in Sam's living room.
Remarkably, Sam knocks down 6 pins on every bowl, and Carlos knocks down 9 pins on every bowl. At the end of the day, Sam and Carlos have knocked down the same total number of pins.

What is the least number of total pins that Sam and Carlos could have each knocked down?

Answer 1

Answer:

The minimum number must be multiple of both 8 and 9 so that they could have same points.

Since 8=2³ and 9=3², there is no common factors, the minimum number will be 8*9=72

So the answer is 72

Answer 2

Answer:

LCM of 8,9 = 2x2x2x3x3= 72

The least number of total pins that Sam and Carlos could have each knocked

down = 72 pins
