    the counter example involves finding a number that can be divided* by 2 but not 4. work through each number and you will find one. *everything is divisible by everything. the missing language here is that the "answer" must be a whole number.

    you're looking for a number that's divisible by 2, but not 4 you want to disprove the claim that "Any number that is divisible by 2 is also divisible by 4"

    dude 12 = 4*3 = 2 *6 look for a number that 2 can go into but not 4.

    correct, 18 is divisible by 2 (ie 2 is a factor of 18) but not divisible by 4 (ie 4 is not a factor of 18)
