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 57,191,339, 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 | 57,191,339 | |
| -1 | -57,191,339 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,191,339.
Example:
1 x 57,191,339 = 57,191,339
and
-1 x -57,191,339 = 57,191,339
Notice both answers equal 57,191,339
With that explanation out of the way, let's continue. Next, we take the number 57,191,339 and divide it by 2:
57,191,339 ÷ 2 = 28,595,669.5
If the quotient is a whole number, then 2 and 28,595,669.5 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 | 57,191,339 | |
| -1 | -57,191,339 |
Now, we try dividing 57,191,339 by 3:
57,191,339 ÷ 3 = 19,063,779.6667
If the quotient is a whole number, then 3 and 19,063,779.6667 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 | 57,191,339 | |
| -1 | -57,191,339 |
Let's try dividing by 4:
57,191,339 ÷ 4 = 14,297,834.75
If the quotient is a whole number, then 4 and 14,297,834.75 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 | 57,191,339 | |
| -1 | 57,191,339 |
If you did it right, you will end up with this table:
| 1 | 47 | 73 | 79 | 211 | 3,431 | 3,713 | 5,767 | 9,917 | 15,403 | 16,669 | 271,049 | 723,941 | 783,443 | 1,216,837 | 57,191,339 |
| -1 | -47 | -73 | -79 | -211 | -3,431 | -3,713 | -5,767 | -9,917 | -15,403 | -16,669 | -271,049 | -723,941 | -783,443 | -1,216,837 | -57,191,339 |
