60 is 2 x 2 x 3 x 5 so it cannot be written as the product of only two prime numbers.
The five prime numbers that multiply together to equal 420 are 2, 2, 3, 5, and 7. This can be expressed as (2^2 \times 3 \times 5 \times 7 = 420). Note that while 2 is repeated, all other numbers listed are distinct prime numbers.
nothing!
As a product of its prime factors: 2*3*5 = 30
2 x 3 x 13 = 78 That is the prime factorization of the number 78.
3, 7 and 11

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
