Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 6,317,815, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 6,317,815 | |
| -1 | -6,317,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,317,815.
Example:
1 x 6,317,815 = 6,317,815
and
-1 x -6,317,815 = 6,317,815
Notice both answers equal 6,317,815
With that explanation out of the way, let's continue. Next, we take the number 6,317,815 and divide it by 2:
6,317,815 ÷ 2 = 3,158,907.5
If the quotient is a whole number, then 2 and 3,158,907.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 6,317,815 | |
| -1 | -6,317,815 |
Now, we try dividing 6,317,815 by 3:
6,317,815 ÷ 3 = 2,105,938.3333
If the quotient is a whole number, then 3 and 2,105,938.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 6,317,815 | |
| -1 | -6,317,815 |
Let's try dividing by 4:
6,317,815 ÷ 4 = 1,579,453.75
If the quotient is a whole number, then 4 and 1,579,453.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 6,317,815 | |
| -1 | 6,317,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 107 | 241 | 245 | 535 | 749 | 1,205 | 1,687 | 3,745 | 5,243 | 8,435 | 11,809 | 25,787 | 26,215 | 59,045 | 128,935 | 180,509 | 902,545 | 1,263,563 | 6,317,815 |
| -1 | -5 | -7 | -35 | -49 | -107 | -241 | -245 | -535 | -749 | -1,205 | -1,687 | -3,745 | -5,243 | -8,435 | -11,809 | -25,787 | -26,215 | -59,045 | -128,935 | -180,509 | -902,545 | -1,263,563 | -6,317,815 |
