1 and 7.
Nothing.. Because 21 is a Prime number
There is no number that goes into both. must be a trick questionthis is another person not the same one :)the number that goes into 12 and 21 is 3 which is a 5th grade problemwho ever said theres no number that goes into 12 and 21 is WRONG!
The number is 1.
14. If you have the numbers in order like so: 7,9,11,14,21 you can see that 21 is the greater number. You then subtract 21 from the smallest number, 7, and you get 14.
1 and 7.
21=3x714=2x77 is the greatest common factor
When figuring out what number goes both into 21 and 28, you should look at the factor paris. 21: 1 x 21, 3 x 7 28: 1, 28, 2 x 14, 4 x 7 7 goes into both 21 and 28.
1, 2, 3, 6, 7, 14, 21, 42

21 is composite number because it has more than one number that goes into it
No even number gose in 21. In fact there is none that goes in 21, either.
Because 14 goes into 21 1 and 1/2 times.
