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 57,147,311, 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 | 57,147,311 | |
| -1 | -57,147,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,147,311.
Example:
1 x 57,147,311 = 57,147,311
and
-1 x -57,147,311 = 57,147,311
Notice both answers equal 57,147,311
With that explanation out of the way, let's continue. Next, we take the number 57,147,311 and divide it by 2:
57,147,311 ÷ 2 = 28,573,655.5
If the quotient is a whole number, then 2 and 28,573,655.5 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 | 57,147,311 | |
| -1 | -57,147,311 |
Now, we try dividing 57,147,311 by 3:
57,147,311 ÷ 3 = 19,049,103.6667
If the quotient is a whole number, then 3 and 19,049,103.6667 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 | 57,147,311 | |
| -1 | -57,147,311 |
Let's try dividing by 4:
57,147,311 ÷ 4 = 14,286,827.75
If the quotient is a whole number, then 4 and 14,286,827.75 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 | 57,147,311 | |
| -1 | 57,147,311 |
If you did it right, you will end up with this table:
| 1 | 13 | 149 | 163 | 181 | 1,937 | 2,119 | 2,353 | 24,287 | 26,969 | 29,503 | 315,731 | 350,597 | 383,539 | 4,395,947 | 57,147,311 |
| -1 | -13 | -149 | -163 | -181 | -1,937 | -2,119 | -2,353 | -24,287 | -26,969 | -29,503 | -315,731 | -350,597 | -383,539 | -4,395,947 | -57,147,311 |
