Let us consider the factors which sum up to 29:
1x28=28
2x27=54
3x26=78
4x25=100
5x24=120
6x23=132
.
.
.
11x18=198
12x17=204
13x16=208
14x15=210
15x14=210
16x13=208
.
.
.
28x1=28
As such, we can seee that 14 and 15 form the largest product, and that as difference between the 2 factors decreases, their multiple increases at a decreasing rate.
