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 57,308,713, 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 | 57,308,713 | |
| -1 | -57,308,713 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,308,713.
Example:
1 x 57,308,713 = 57,308,713
and
-1 x -57,308,713 = 57,308,713
Notice both answers equal 57,308,713
With that explanation out of the way, let's continue. Next, we take the number 57,308,713 and divide it by 2:
57,308,713 ÷ 2 = 28,654,356.5
If the quotient is a whole number, then 2 and 28,654,356.5 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 | 57,308,713 | |
| -1 | -57,308,713 |
Now, we try dividing 57,308,713 by 3:
57,308,713 ÷ 3 = 19,102,904.3333
If the quotient is a whole number, then 3 and 19,102,904.3333 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 | 57,308,713 | |
| -1 | -57,308,713 |
Let's try dividing by 4:
57,308,713 ÷ 4 = 14,327,178.25
If the quotient is a whole number, then 4 and 14,327,178.25 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 | 57,308,713 | |
| -1 | 57,308,713 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 101 | 707 | 1,111 | 7,369 | 7,777 | 51,583 | 81,059 | 567,413 | 744,269 | 5,209,883 | 8,186,959 | 57,308,713 |
| -1 | -7 | -11 | -77 | -101 | -707 | -1,111 | -7,369 | -7,777 | -51,583 | -81,059 | -567,413 | -744,269 | -5,209,883 | -8,186,959 | -57,308,713 |
