Best ResponseYou've already chosen the best response.1The 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?

Best ResponseYou've already chosen the best response.1So 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
