The product of the fourth and sixth prime numbers is 91.
The number 455 ends with a 5, thus it is divisible by 5; 455/5 = 91. 91 is a tricky number, because it's hard to tell that it's not prime. If you couldn't see that 91 is divisible by 7, then I recommend expanding your multiplication table for 7. 91/7 = 13, and since both 7 and 13 are prime numbers, the prime factorization of 455 is 5 X 7 X 13.
91 is the only composite factor of 91. 7 and 13 are prime.
They are: 7 times 13 = 91
As a product of its prime factors: 7*13 = 91
