Seven and three are both prime numbers, therefore their only factors are one and itself. Nine's factors are 9,1, and 3. 3 Goes into 3 evenly, but doesnt go into 7 evenly. Therefore the only number that fits into 9, 7, and 3 evenly is 1. Hope this helps!
i dont know if it counts as a mixed number but 3 should be the answer because 7 goes into 21 EVENLY 3 times and there is nothing left over.
5 and 7 are prime numbers. and 3 goes into 9, so the only number that goes into 5, 7, and 9 is 1. They are what we call "relatively prime", even though 9 is not prime, because they have no common factors other than 1.
1 and 7.

They are: 2, 3 and 7
It is one
Just 1.
The number 7. 7 goes into 21 3 times; 7 goes into 49 7 times.
1, 3, 7, 21.
Just 1.
Only the number 1.
The number is 1.
not one number goes into 6 and 7 unless it is 1. the numbers 1, 2, 3, and 6 go into 6. only 1 goes into 7 because 7 is a prime number
