1, 3, 17, 51.
They are: 1 and 51
The numbers 1 and 3.
3 and 119 7 and 51
1, 3, 5, 15.
1 and 3 will go into both numbers evenly leaving no remainders
The numbers that go into 30 are1, 2, 3, 5, 30, 15, 10, 6
1 and 3 go into both.
No, only these numbers can: 1, 3, 5, 15.
These will: 1, 3, 5, 15, 17, 51, 85, 255.
3 goes into 51 evenly 17 times So does 25 1/2 (twice). I am wondering if you want only whole numbers? You could go on forever with fractions and decimals.
No. 51 is not evenly divisible by 12.
