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 2,573,585, 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 | 2,573,585 | |
| -1 | -2,573,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,573,585.
Example:
1 x 2,573,585 = 2,573,585
and
-1 x -2,573,585 = 2,573,585
Notice both answers equal 2,573,585
With that explanation out of the way, let's continue. Next, we take the number 2,573,585 and divide it by 2:
2,573,585 ÷ 2 = 1,286,792.5
If the quotient is a whole number, then 2 and 1,286,792.5 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 | 2,573,585 | |
| -1 | -2,573,585 |
Now, we try dividing 2,573,585 by 3:
2,573,585 ÷ 3 = 857,861.6667
If the quotient is a whole number, then 3 and 857,861.6667 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 | 2,573,585 | |
| -1 | -2,573,585 |
Let's try dividing by 4:
2,573,585 ÷ 4 = 643,396.25
If the quotient is a whole number, then 4 and 643,396.25 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 | 2,573,585 | |
| -1 | 2,573,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 139 | 161 | 529 | 695 | 805 | 973 | 2,645 | 3,197 | 3,703 | 4,865 | 15,985 | 18,515 | 22,379 | 73,531 | 111,895 | 367,655 | 514,717 | 2,573,585 |
| -1 | -5 | -7 | -23 | -35 | -115 | -139 | -161 | -529 | -695 | -805 | -973 | -2,645 | -3,197 | -3,703 | -4,865 | -15,985 | -18,515 | -22,379 | -73,531 | -111,895 | -367,655 | -514,717 | -2,573,585 |
