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 57,071,315, 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 | 57,071,315 | |
| -1 | -57,071,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,071,315.
Example:
1 x 57,071,315 = 57,071,315
and
-1 x -57,071,315 = 57,071,315
Notice both answers equal 57,071,315
With that explanation out of the way, let's continue. Next, we take the number 57,071,315 and divide it by 2:
57,071,315 ÷ 2 = 28,535,657.5
If the quotient is a whole number, then 2 and 28,535,657.5 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 | 57,071,315 | |
| -1 | -57,071,315 |
Now, we try dividing 57,071,315 by 3:
57,071,315 ÷ 3 = 19,023,771.6667
If the quotient is a whole number, then 3 and 19,023,771.6667 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 | 57,071,315 | |
| -1 | -57,071,315 |
Let's try dividing by 4:
57,071,315 ÷ 4 = 14,267,828.75
If the quotient is a whole number, then 4 and 14,267,828.75 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 | 57,071,315 | |
| -1 | 57,071,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 139 | 695 | 973 | 4,865 | 11,731 | 58,655 | 82,117 | 410,585 | 1,630,609 | 8,153,045 | 11,414,263 | 57,071,315 |
| -1 | -5 | -7 | -35 | -139 | -695 | -973 | -4,865 | -11,731 | -58,655 | -82,117 | -410,585 | -1,630,609 | -8,153,045 | -11,414,263 | -57,071,315 |
