There are only 5 prime integer factors. There are 44 integer factors. These guys:

With one exception, they are not all prime numbers, but remember that Skip asked for: > 358358=*/x1, x2, x3, x4, x5 > How many different combinations of 5 integersx1, x2, x3, x4, x5 solve this > equality? (Different orders don't count) And it seems to me that there are 44 of those?
