Is there a quick way to divide numbers?
In: Mathematics
That depends on how large of numbers you are looking at and how accurate you want division to be.
Here’s a quick way to know when a number can be evenly divided by these certain numbers:
* 10 if the number ends in 0
* 9 when the digits are added together and the total is evenly divisible by 9
* 8 if the last three digits are evenly divisible by 8 or are 000
* 6 if it is an even number and when the digits are added together the answer is evenly divisible by 3
* 5 if it ends in a 0 or 5
* 4 if it ends in 00 or a two digit number that is evenly divisible by 4
* 3 when the digits are added together and the result is evenly divisible by the number 3
* 2 if it ends in 0, 2, 4, 6, or 8
