Hank has 744 black coins and 527 white coins. He wants to arrange them in stacks of the same kind of coins (since if differently-colored coins are placed together in the same stack, discrimination will eventually result in hate crimes and lynchings). In other words, all coins in a stack are all black or all white. If each stack has the same number of coins, what is the minimum number of stacks needed?
