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 7,631,585, 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 | 7,631,585 | |
| -1 | -7,631,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,631,585.
Example:
1 x 7,631,585 = 7,631,585
and
-1 x -7,631,585 = 7,631,585
Notice both answers equal 7,631,585
With that explanation out of the way, let's continue. Next, we take the number 7,631,585 and divide it by 2:
7,631,585 ÷ 2 = 3,815,792.5
If the quotient is a whole number, then 2 and 3,815,792.5 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 | 7,631,585 | |
| -1 | -7,631,585 |
Now, we try dividing 7,631,585 by 3:
7,631,585 ÷ 3 = 2,543,861.6667
If the quotient is a whole number, then 3 and 2,543,861.6667 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 | 7,631,585 | |
| -1 | -7,631,585 |
Let's try dividing by 4:
7,631,585 ÷ 4 = 1,907,896.25
If the quotient is a whole number, then 4 and 1,907,896.25 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 | 7,631,585 | |
| -1 | 7,631,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 137 | 685 | 857 | 1,781 | 4,285 | 8,905 | 11,141 | 55,705 | 117,409 | 587,045 | 1,526,317 | 7,631,585 |
| -1 | -5 | -13 | -65 | -137 | -685 | -857 | -1,781 | -4,285 | -8,905 | -11,141 | -55,705 | -117,409 | -587,045 | -1,526,317 | -7,631,585 |
