Answer: 7
3 x 7 = 21
4 x 7 = 28.
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.
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.
No, the only one that does is three. (1, 3, 7, 21)
The numbers that go into 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84
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.
The numbers that can go into both 21 and 100 are their common divisors. The divisors of 21 are 1, 3, 7, and 21, while the divisors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. The only common divisor between the two is 1. Therefore, the only number that can go into both 21 and 100 is 1.
1 and 7 will go into both numbers evenly leaving no remainders
1,2,4,7,14, and 28.
