How about: 29+67 = 96
31 & 67
31 & 67
They are: 1*67 = 67
7 x 67 = 469
They are: 7 times 67 = 469
If X and Y are the first two numbers, then the third must be = 67 - (X+Y)
1*67
No two even numbers can be multiplied to get 67.
1 x 469 and 7 x 67 = 469
No primes can be found such that they can sum to 67.
Two of them and they are 61 and 67
