I agree with you bissy

However, for 1) 292 = 2 * 146. I think that is what Grace meant.

I believe the problem meant was:
WHAT 2 NUMBERS MAKE...
1.) 29
2.) 63
3.) 70
4.) 34
5.) 120
6.) 66
as a product of two factors?

My answer is:

29 = 1 X 29 (29 is a prime number, and a prime number's only factors are 1 and the number itself).

For all the others, you have more interesting options. Look for prime factors. Is the number divisible by 2? By 3? By 5? By 7? By 11?

There could be more than one answer. For example, 63 = 9 X 7, but 9 = 3 X 3, so 63 = 3 X 3 X 7. You can pick 3 or 7 as one of the factors to make two answers that do not use "1 X " :
63 = 3 X 21
63 = 7 X 9
