Oh, dude, 9 and 21 both go into numbers that are multiples of both 9 and 21. So, like, they can go into numbers like 63, 126, 189, and so on. It's just basic math, nothing too mind-blowing.
The numbers that go into 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84
1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84.
21
1 ,3 ,7 ,21
28?
Nothing can go evenly into 21 or 17. They are both odd numbers and therefore cannot be evenly divided.
1, 2.

3 can go into both these numbers 72/3= 24 21/3= 7
the numbers that can go into 28 are 1,2,4,7,14 and 28.
That would be 1--no numbers besides 1 go into both 10 and 21.
The numbers that go into 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84
No, the only one that does is three. (1, 3, 7, 21)
Oh, dude, that's an easy one. So, what can go into 21 and 39? Well, technically, the numbers that can go into both 21 and 39 are 1 and 3. Like, it's not rocket science, but hey, math can be a little sneaky sometimes.
1 and 7 will go into both numbers evenly leaving no remainders
1,2,4,7,14, and 28.
