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 57,580,805, 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 | 57,580,805 | |
| -1 | -57,580,805 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,580,805.
Example:
1 x 57,580,805 = 57,580,805
and
-1 x -57,580,805 = 57,580,805
Notice both answers equal 57,580,805
With that explanation out of the way, let's continue. Next, we take the number 57,580,805 and divide it by 2:
57,580,805 ÷ 2 = 28,790,402.5
If the quotient is a whole number, then 2 and 28,790,402.5 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 | 57,580,805 | |
| -1 | -57,580,805 |
Now, we try dividing 57,580,805 by 3:
57,580,805 ÷ 3 = 19,193,601.6667
If the quotient is a whole number, then 3 and 19,193,601.6667 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 | 57,580,805 | |
| -1 | -57,580,805 |
Let's try dividing by 4:
57,580,805 ÷ 4 = 14,395,201.25
If the quotient is a whole number, then 4 and 14,395,201.25 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 | 57,580,805 | |
| -1 | 57,580,805 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 67 | 145 | 335 | 1,943 | 5,927 | 9,715 | 29,635 | 171,883 | 397,109 | 859,415 | 1,985,545 | 11,516,161 | 57,580,805 |
| -1 | -5 | -29 | -67 | -145 | -335 | -1,943 | -5,927 | -9,715 | -29,635 | -171,883 | -397,109 | -859,415 | -1,985,545 | -11,516,161 | -57,580,805 |
