Add them up. The factors of 9 are 1, 3 and 9. The sum of the factors is 13.
The factors of 9 are 1, 3, and 9. 1 + 3 + 9 = 13
2 3 5 7 11 13 17 19 23 29 31 and 37 are the prime numbers you can use. Possible options are: 3 + 37 = 40 11 + 29 = 40 2 + 7 + 31 = 40 3 + 7 + 13 + 17 = 40 17 + 23 = 40 3 + 7 + 13 + 17 = 40
The factors of 21 that add up to 8 are 1 and 7.
The four factors of 33 add up to 48.
The two numbers that add up to -13 and multiply to 40 are -8 and -5. When you add them together, -8 + (-5) equals -13, and when you multiply them, -8 * -5 equals 40. Thus, the solution is correct.
The four factors of 33 add up to 48.
The only number between 30 and 40 with distinct prime factors which add up to 12 is 35.
