Correct? After Akamaibrah crucified me on prime factorization, I start to doubt in any problem.
Didn't mean to crush you on that problem. Just wanted to show your stubborn butt that giving someone a formula
to get the answer
is NOT the same as showing them how to solve the problem
BTW, i got the same answer as you: 246. There is no reason to doubt when you have a rationale for coming up with your answer!
