boolean commonFactor(num1, num2, divisor): Given 2 numbers and a divisor, determine if the divisor is a factor of both numbers. A divisor is a factor of a number if it divides that number evenly (the remainder will be zero). If the divisor is 0, the division is impossible, so return false. You can use the % "mod" operator to make this determination. RUBRIC: It is not enough to just solve the problem. Make sure you use PROPER INDENTATION. You MUST use CURLY BRACKETS for all loops and if/else statements. Also, the more EFFICIENT your solution, the higher your grade. If you have extraneous (superfluous / unnecessary) code, deductions will be taken.
