1&20
2&10
5&4
I think they are the only factors of 20 but I could be wrong so the first and second '1&20 and 2&10' should be the answer 🙂

2. nijanicole164 says:

20/4 = 5 however,

2 x 2.5 = 5 (it doesn't work, cannot have decimals)

hope this helps

3. s5177 says:

5 bc 5 times 4 and its not a multiple of 4

4. jahkin0256 says:

5 can go into 4, 4 times so 5x4=20

5. km8115 says:

The best way to do this is just to simply list at all of the possible factors of 20 and then take out those which are multiples of 2:

20 = 1, 2, 4, 5, 10, 20

Minus the multiples of 2:

Leaves only 1 and 5

The only option of these two on the list is 5 so the answer must be 5

The awnser is five I hope I helped you

7. kat6282 says:

4×5=20 because 4 can go to 20

45, 60, 330

GCF= 15

GCF - greatest Common Factor

9. kenxkeith says:

5 is the answer because 2 do not have 5 in it

10. zenzen24 says:

5, 10, 1, 2, 20, that your factors, there are probably more but those I know off that up of my head
