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 9,688,627, 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 | 9,688,627 | |
| -1 | -9,688,627 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,688,627.
Example:
1 x 9,688,627 = 9,688,627
and
-1 x -9,688,627 = 9,688,627
Notice both answers equal 9,688,627
With that explanation out of the way, let's continue. Next, we take the number 9,688,627 and divide it by 2:
9,688,627 ÷ 2 = 4,844,313.5
If the quotient is a whole number, then 2 and 4,844,313.5 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 | 9,688,627 | |
| -1 | -9,688,627 |
Now, we try dividing 9,688,627 by 3:
9,688,627 ÷ 3 = 3,229,542.3333
If the quotient is a whole number, then 3 and 3,229,542.3333 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 | 9,688,627 | |
| -1 | -9,688,627 |
Let's try dividing by 4:
9,688,627 ÷ 4 = 2,422,156.75
If the quotient is a whole number, then 4 and 2,422,156.75 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 | 9,688,627 | |
| -1 | 9,688,627 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 101 | 157 | 611 | 1,313 | 2,041 | 4,747 | 7,379 | 15,857 | 61,711 | 95,927 | 206,141 | 745,279 | 9,688,627 |
| -1 | -13 | -47 | -101 | -157 | -611 | -1,313 | -2,041 | -4,747 | -7,379 | -15,857 | -61,711 | -95,927 | -206,141 | -745,279 | -9,688,627 |
