Question 1032804
We are asked to find a common multiple of 48, 72, and 108...
One way is to merely list the multiples of each and see the first number common in all three lists...like this...
48,96,144,192,240, etc.
72,144,216,288,360, etc.
108,216,324,432,540, etc.
The other way is to do a prime factorization and go from there...
