nothing!
As a product of its prime factors: 2*3*5 = 30
3, 7 and 11
13 times 17 = 221
60 is 2 x 2 x 3 x 5 so it cannot be written as the product of only two prime numbers.
They are: 2*2*2*7 = 56

There are no two prime numbers that multiply to 24. You need four numbers (even though one appears 3 times).
Actually, two prime numbes time each other equal 33. They are 3 times 11.
3 times 3 times 2 equals 18
1 times 71 = 71 which is also a prime number
