The answer is: 5 x 5 x 7 x 7 = 1,225
They are: 7 times 13 = 91
They are: 1 times 19 = 19 which is a prime number
They are 1 times 19 = 19 which is a prime number
Only once - thanks to the unique prime factorisation theorem.

Three times three times three.
They are: 7 times 13 = 91
They are: 1 times 19 = 19 which is a prime number
They are 1 times 19 = 19 which is a prime number
There are no two prime numbers that multiply to 24. You need four numbers (even though one appears 3 times).
They are: 1 times 107 = 107 which is also a prime number
Only once - thanks to the unique prime factorisation theorem.

three times 2 and two times 5 that is 2*2*2*5*5
They are only: 1 times 2003 = 2003 because it is a prime number
You can multiply 2 times 11 times 5 to make 110! (2x11=22x5=110)
Yes! 2 times 5 equals 10. 10 times 3 equals 30. So, the prime numbers that multiply together to make 30, are, 2, 3 and 5.
