If you mean whole numbers, then they are:
1, 2, 3, 5, 9, 10
A factor can divide into its multiple evenly.
2 and 60 will divide evenly into 120.
7 is not a factor of 90. It does not divide into 90 evenly.
1,2,3,5,6,9,10,15,18,90 These number go into 90 evenly
The six times tables are any and all multiples of 6. Therefore, any numbers that divide evenly by 6 will be in the six times tables, and any that don't won't be. 90/6 = 15, and so 90 does divide evenly by 6. Thus, 90 is in the six times tables.
These numbers divide into 15 evenly: 1 3 5 and 15.
These are the numbers that divide into 28 evenly: 1, 2, 4, 7, 14, 28.
1, 2, 4, 5, 10, and 20 divide evenly into 20.

They are called factors or divisors.
