Alexei and Boris both have a whole number of chocolates, lollipops and toffees, and the product of the number of each boy's of chocolates, lollipops and toffees is 336. It is known that:

(A) Each boy has fewer chocolates than lollipops.

(B) For each boy, the product of the number of chocolates and lollipops equals the total number of candies he has.

 re: Computer solution AND 7 AND 48 | Comment 10 of 11 |
(In reply to Computer solution by Ken Haley)

There are 20 possible factors:

You omitted 7 and 48.....

Generally speaking,   if a number N may be decomposed into primes:  N=2^a1*3^a2*5^a3*       ... p^aZ

then the number of possible divisors is (a1+1)*(a2+1)*(a3+1)*...*(aZ+1)

In our case  5*2*2=20
