How to do question 4?
Nutka1998 [239]
Marie states that any integer greater than 4 will always get an even number of factors.

This can be proven wrong by (for example) 12.

12 has these factors:

1 x 12
2 x 6
3 x 4

12 has an ODD number of factor pairs.

Another example is 28.

28:
1 x 28
2 x 14
4 x 7

28 has an odd number of factor pairs.

I hope this helps!
