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 57,131,555, 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 | 57,131,555 | |
| -1 | -57,131,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,131,555.
Example:
1 x 57,131,555 = 57,131,555
and
-1 x -57,131,555 = 57,131,555
Notice both answers equal 57,131,555
With that explanation out of the way, let's continue. Next, we take the number 57,131,555 and divide it by 2:
57,131,555 ÷ 2 = 28,565,777.5
If the quotient is a whole number, then 2 and 28,565,777.5 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 | 57,131,555 | |
| -1 | -57,131,555 |
Now, we try dividing 57,131,555 by 3:
57,131,555 ÷ 3 = 19,043,851.6667
If the quotient is a whole number, then 3 and 19,043,851.6667 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 | 57,131,555 | |
| -1 | -57,131,555 |
Let's try dividing by 4:
57,131,555 ÷ 4 = 14,282,888.75
If the quotient is a whole number, then 4 and 14,282,888.75 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 | 57,131,555 | |
| -1 | 57,131,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 47 | 65 | 235 | 611 | 3,055 | 18,701 | 93,505 | 243,113 | 878,947 | 1,215,565 | 4,394,735 | 11,426,311 | 57,131,555 |
| -1 | -5 | -13 | -47 | -65 | -235 | -611 | -3,055 | -18,701 | -93,505 | -243,113 | -878,947 | -1,215,565 | -4,394,735 | -11,426,311 | -57,131,555 |
