a * b = 169
a + b = 7
a = 7 - b
(7 - b) * b = 169
-b^2 + 7b - 169 = 0
Then you just plug those coefficients into the quadratic formula and solve for b, then plug that solution into an equation for a. I can tell you though, that they're going to be negative, and they're not going to be integers.
1 x 507, 3 x 169, 13 x 39.
1 x 169 13 x 13
13 x 13
169
The 2 numbers that multiply together to equal 678 are 6 and 113.
13*13
How about: 13 times 13 = 169
1 x 507, 3 x 169, 13 x 39.
The two numbers can be any two numbers so that when they are added, they equal 338.
1 x 169 13 x 13
The two numbers you can multiply together to equal 782 are 23 by 34.
The two numbers you multiply together to equal 391 are 17 by 23.
13 x 13
