Oh, dude, that's an easy one. So, what can go into 21 and 39? Well, technically, the numbers that can go into both 21 and 39 are 1 and 3. Like, it's not rocket science, but hey, math can be a little sneaky sometimes.
Suppose x = sqrt(3*a) where a is an integer that is not divisible by 3. then x2 = 3*a which is divisible by 3. but x is not even rational and so is not an integer and is certainly not divisible by 3.
