find two positive numbers whose product is a maximum. 1.) the sum is s.
16prime + prime = (sum) sum is 16or13 + 3 =16
There are no numbers to circle!
The only two prime numbers for which this can be the case are 2 and 5 - since one of the prime numbers has to be even.
67
17 and 3 are two prime numbers whose sum is 20. Their product is 51.
Two and 73.
2 and 467 are two prime numbers whose sum is 469.
There are no such numbers.
3 and 17
They are 13 and 17
37 and 5
17 and 19
23 and 29
There are no two primes whose sum is 209.
23 and 29
They are: 29+19 = 48
