51 and 8
1 x 26, 2 x 13.
There are many possible pairs of numbers. One such is 1 and -380.
(56,2)(28,4)(16,7)(14,8)
The prime numbers that you multiply together to get 150 are 2, 3, 5, and 5.
8 x 8 x 9
2 x 6 = 12
5*7*13 = 455
yes it is possible
3 * 12456789
You could do that with 1, 5, and 49, or with 5, 7, and 7, etc.
Mulitply by 2 and then divide by 3 (or divide by 3 and then multiply by 2).
Assuming you mean using only positive whole numbers: 1 x 61 (only as 61 is a prime number)
