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 57,285,985, 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 | 57,285,985 | |
| -1 | -57,285,985 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,285,985.
Example:
1 x 57,285,985 = 57,285,985
and
-1 x -57,285,985 = 57,285,985
Notice both answers equal 57,285,985
With that explanation out of the way, let's continue. Next, we take the number 57,285,985 and divide it by 2:
57,285,985 ÷ 2 = 28,642,992.5
If the quotient is a whole number, then 2 and 28,642,992.5 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 | 57,285,985 | |
| -1 | -57,285,985 |
Now, we try dividing 57,285,985 by 3:
57,285,985 ÷ 3 = 19,095,328.3333
If the quotient is a whole number, then 3 and 19,095,328.3333 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 | 57,285,985 | |
| -1 | -57,285,985 |
Let's try dividing by 4:
57,285,985 ÷ 4 = 14,321,496.25
If the quotient is a whole number, then 4 and 14,321,496.25 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 | 57,285,985 | |
| -1 | 57,285,985 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 31 | 115 | 155 | 713 | 3,565 | 16,069 | 80,345 | 369,587 | 498,139 | 1,847,935 | 2,490,695 | 11,457,197 | 57,285,985 |
| -1 | -5 | -23 | -31 | -115 | -155 | -713 | -3,565 | -16,069 | -80,345 | -369,587 | -498,139 | -1,847,935 | -2,490,695 | -11,457,197 | -57,285,985 |
