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 57,903,131, 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 | 57,903,131 | |
| -1 | -57,903,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,903,131.
Example:
1 x 57,903,131 = 57,903,131
and
-1 x -57,903,131 = 57,903,131
Notice both answers equal 57,903,131
With that explanation out of the way, let's continue. Next, we take the number 57,903,131 and divide it by 2:
57,903,131 ÷ 2 = 28,951,565.5
If the quotient is a whole number, then 2 and 28,951,565.5 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 | 57,903,131 | |
| -1 | -57,903,131 |
Now, we try dividing 57,903,131 by 3:
57,903,131 ÷ 3 = 19,301,043.6667
If the quotient is a whole number, then 3 and 19,301,043.6667 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 | 57,903,131 | |
| -1 | -57,903,131 |
Let's try dividing by 4:
57,903,131 ÷ 4 = 14,475,782.75
If the quotient is a whole number, then 4 and 14,475,782.75 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 | 57,903,131 | |
| -1 | 57,903,131 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 59 | 143 | 649 | 767 | 6,863 | 8,437 | 75,493 | 89,219 | 404,917 | 981,409 | 4,454,087 | 5,263,921 | 57,903,131 |
| -1 | -11 | -13 | -59 | -143 | -649 | -767 | -6,863 | -8,437 | -75,493 | -89,219 | -404,917 | -981,409 | -4,454,087 | -5,263,921 | -57,903,131 |
