13
The numbers are 9, 10 and 11 with a sum of 30.
11
5 and 6 are factors of 30 that, when added together, provide a sum of 11.
The sum of the positive whole-number factors of 30 is 72.
The numbers are 5 and 6.
The prime factors of 30 are: 2 + 3 + 5 = 10
20 and 30.
The factors of 29 are 1 and 29. Their sum is 30.
The prime numbers of: 23 plus 7 = 30 Also, 11 + 19 = 30 and 13 + 17 = 30
20 and 30 All numbers have at least one common factor.
Goldbach's conjecture says that every even number greater than two can be expressed as the sum of 2 primes. If 30 could not be expressed as the sum of two primes, then this would disprove the conjecture. As it is, 30 can be expressed as the sum of two primes. You can express it as 11+19. Thus, Goldbach's conjecture holds in this case.
11 + 19 = 30
product means multiplication sum means adding. 6 * 5 = 30 6 + 5 = 11
Add them up. The prime factors of 30 are 2, 3 and 5. You can handle the rest.
