The definition of prime means that the you can only get the number by multiplying itself by 1. For instance 2: You can only get two by multiplying 1 and 2 together. So which provided answer fits that definition AND equals 28 once you multiply it out?
sorry doun't understand
It's okay! Let's make a factoring tree.
28 is the number you start with. |dw:1442605156919:dw|

So what I did was, I broke it down. 28 is equal to 4 * 7, but we want to get all the way to the lowest numbers possible, so we kept going.
4 is equal to 2 * 2 so you write that below the four. Then 7 is a prime number already so you put 7 * 1
So, the prime numbers you need to make 28 are: 2 * 2 * 7 * 1
Does that make more sense?
i think? so sorry
