What you are trying to find is the smallest number into which you can divide 3, 7 and 8. You should note that 3, 7 and 8 don't share any divisors. Thus to get a number that 7 and 8 divides you need to multiply them, i.e. it's 56. Now what can you do with the 3 and your new number 56? Your teacher should know this or they're not really teaching you math. Penny
