14
3.5 you multiply it by 2
not always. 9-7=2 while 7-9=-2
prime factorizing, 63 = 3*3*7 and 28 = 2*2*7, so the answer is 7.
Any multiple of 42.
70 is the smallest number that has prime factors of 2,5 and 7
The numbers that can go into 14 are 1,14,7,2.
The factors of 196 are 2 and 7 (7*7*2*2=196) so any number that is a multiple of those terms will go in evenly: 2, 4, 7, 14, 49, and of course 1 and 196.
7 and 5 are prime numbers, but 3*2=6
14 = 2*7 49 = 7*7 So 1, -1, 7, -7 all go into both 14 and 49.
in the number 22 the number 2 can go into 22 11 times in the number 35 the number 5 can go into 35 7 times
