List its factors and scratch off the ones that add up to 100 or more. You'll end up with:
4, 90
5, 72
6, 60
8, 45
9, 40
10, 36
12, 30
15, 24
18, 20

360 = 2*2*2*3*3*5
First: Figure out how many differernt pairs of numbers, whose product will be 360, from this list of factors.
Second: Determine which pairs sum to 100 or greater.
There are very few pairs with a LARGE factor of 360: (180*2), (120*3), and (90*4). Only the first two sums are too large. As the pairs get closer in value their sum grows less.

30 x 12 or 10 x 36 or 5 x 72 or 15 x 24 or 20 x 18 or 40 x 9 or 60 x 6

List the factors of 360 pairwise, and see what happens!
1 x 360
2 x 180
3 x 120
4 x 90
5 x 72
6 x 60
8 x 45
9 x 40
10 x 36
12 x 30
15 x 24
18 x 20
All but the top three will do.
