What do I do now?

Nvm. Got it.

if(num % 2 == 0){ int num1 = num/2 int num2 = num/2 return isEven(num1) && isEven(num2)
}

if(num % 3 == 0){ int num1 = num/3 int num2 = num/3 int num3 = num/3 return isEven(num1) && isEven(num2) && isEven(num3) }

Obviously we need to check each part of the division to make sure if they are even or not. /s
