-5 and -6
13
6 and 13
They are 9 and 4
6 and 7
This is mathematically impossible. The highest product that you can get with two numbers that make thirteen is 42 (7*6). The lowest sum you can get for two numbers with a product of 155 is 36 (31 and 5). All in all, it's impossible.
5 and 8
8 and 5
7 and 6
36 as a product of its prime factors is 2 x 2 x 3 x 3. Their total is 10. 36 as a product of factors that total 13 is 4 x 9
41 is prime, and 51 factors to 3 * 17. the factors of the sum is 7 and 13, the factors of the product are 41, 3 and 17.
The sum of the positive odd factors of 36 is 13 (1 + 3 + 9 = 13).
The sum of 8 and 5 is 13. There is then no number with which to calculate its product.
Add them up. The factors of 9 are 1, 3 and 9. The sum of the factors is 13.
The factors of 91 are: 1 7 13 91.The prime factors are: 7 x 13The sum of the prime factors = 7 + 13 = 20
The sum of 8 and 5 is 13 The difference of 8 and 5 is 3 So the question is what is the product of 13 and 3 13 X 3= 39
The factors of 169 are 1, 13, and 169, and the prime factors are 13 x 13. 169 is the product of 1 x 169 or of the prime factors 13 x 13.
Take 13 and 17 as an example. Sum is 13 + 17 ie 30, product is 13 x 17 = 221
