1, 3, 5, 11, 15, 33, 55, 165
3 will go into both of these numbers
1, 3, 5 & 15 all divide 15 and 120 exactly.
8.5333
The numbers are 15 and 16.
1, 3, 5, 11, 15, 33, 55, 165
The number 60 can't be divided by 25 and get a whole number.
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60.
Because 1, 3, 5 and 15 are the only positive whole numbers that will divide evenly into 15 with no remainder.
3 will go into both of these numbers
