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 57,687,311, 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 | 57,687,311 | |
| -1 | -57,687,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,687,311.
Example:
1 x 57,687,311 = 57,687,311
and
-1 x -57,687,311 = 57,687,311
Notice both answers equal 57,687,311
With that explanation out of the way, let's continue. Next, we take the number 57,687,311 and divide it by 2:
57,687,311 ÷ 2 = 28,843,655.5
If the quotient is a whole number, then 2 and 28,843,655.5 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 | 57,687,311 | |
| -1 | -57,687,311 |
Now, we try dividing 57,687,311 by 3:
57,687,311 ÷ 3 = 19,229,103.6667
If the quotient is a whole number, then 3 and 19,229,103.6667 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 | 57,687,311 | |
| -1 | -57,687,311 |
Let's try dividing by 4:
57,687,311 ÷ 4 = 14,421,827.75
If the quotient is a whole number, then 4 and 14,421,827.75 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 | 57,687,311 | |
| -1 | 57,687,311 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 167 | 341 | 1,013 | 1,837 | 5,177 | 11,143 | 31,403 | 56,947 | 169,171 | 345,433 | 1,860,881 | 5,244,301 | 57,687,311 |
| -1 | -11 | -31 | -167 | -341 | -1,013 | -1,837 | -5,177 | -11,143 | -31,403 | -56,947 | -169,171 | -345,433 | -1,860,881 | -5,244,301 | -57,687,311 |
