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 57,131,503, 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 | 57,131,503 | |
| -1 | -57,131,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,131,503.
Example:
1 x 57,131,503 = 57,131,503
and
-1 x -57,131,503 = 57,131,503
Notice both answers equal 57,131,503
With that explanation out of the way, let's continue. Next, we take the number 57,131,503 and divide it by 2:
57,131,503 ÷ 2 = 28,565,751.5
If the quotient is a whole number, then 2 and 28,565,751.5 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 | 57,131,503 | |
| -1 | -57,131,503 |
Now, we try dividing 57,131,503 by 3:
57,131,503 ÷ 3 = 19,043,834.3333
If the quotient is a whole number, then 3 and 19,043,834.3333 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 | 57,131,503 | |
| -1 | -57,131,503 |
Let's try dividing by 4:
57,131,503 ÷ 4 = 14,282,875.75
If the quotient is a whole number, then 4 and 14,282,875.75 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 | 57,131,503 | |
| -1 | 57,131,503 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 67 | 89 | 143 | 737 | 871 | 979 | 1,157 | 4,489 | 5,963 | 9,581 | 12,727 | 49,379 | 58,357 | 65,593 | 77,519 | 399,521 | 641,927 | 852,709 | 4,394,731 | 5,193,773 | 57,131,503 |
| -1 | -11 | -13 | -67 | -89 | -143 | -737 | -871 | -979 | -1,157 | -4,489 | -5,963 | -9,581 | -12,727 | -49,379 | -58,357 | -65,593 | -77,519 | -399,521 | -641,927 | -852,709 | -4,394,731 | -5,193,773 | -57,131,503 |
