Selma multiplies the number 9 the two-digit number \overline{AB}, and the three-digit number \overline{CDE}.  She finds that the product of all three numbers is the five-digit number 41409.  Compute the sum \overline{AB} + \overline{CDE}.  (The digits $A,$ $B,$ $C,$ $D,$ and $E$ are not necessarily distinct.)

41409 / 9  =  4601

 

Factorization of 4601 = 43 * 107

 

sum = AB + CDE =   43 + 107  =   150
