Help with Prime Factorization

[RINCONVIEW]

The favorite number is very special. The prime factors of this number do not repeat and are all of the odd prime numbers less than 15. What is the number? We determined that all of the odd prime numbers under 15 are 3,5,7,11 & 13 but can't determine a number in which they are all a prime factor... assuming that if 5 is one of them it would have to be a multiple of 5, but not sure.

Number = 3 * 5 * 7 ...... continue

The prime factors of [a] number do not repeat and [the prime factors] are all of the odd prime numbers less than 15. What is the number?

Multiply the odd primes less than 15 together, to calculate the number.

Multiply > > >the odd primes less than 13 < < < together, to calculate the number.

You meant "the odd primes less than or equal to 13," or "the odd primes less than 15?"

Thanks, lookagain; fixed that. When my subconscious shoves up two alternates, sometimes I take a piece of each. :roll:
