This one you would just use trial and error.

Write down the prime numbers up to $\displaystyle \displaystyle 19$ and work out the products of the four consecutive primes ending in $\displaystyle \displaystyle 11,13,17,19$. - Feb 11th 2011, 03:31 AMHallsofIvy
Why do you assume

*consecutive*primes? - Feb 11th 2011, 03:40 AMProve It

I think that in this question you can just write down the prime factorizations of the 2 given numbers, and the answer will magically appear.
