Prime + Addition = ?
I had 3 numbers:
-
1190
-
7800
-
4641
What is the sum of all the prime factors needed to multiply all of those numbers? Then, divide the sum by itself, add it with all the prime numbers on the calculator. Divide it by 2. After that, multiply it with 210.
The final result is X. What is X - 891?
The answer is 999.
