Many children feel uneasy when it comes to long division especially with 2 or more digit number divisors. To divide a number by 4, they only need to know their 4 times table. To divide a number by 8, they just need to know the 8 times table. But what if they need to divide a number by 54? Do they need to know their 54 times table? No, not if they know how to divide using factors. It is a quick way of dividing without wasting time estimating or guessing.
