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 57,833,891, 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 | 57,833,891 | |
| -1 | -57,833,891 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,833,891.
Example:
1 x 57,833,891 = 57,833,891
and
-1 x -57,833,891 = 57,833,891
Notice both answers equal 57,833,891
With that explanation out of the way, let's continue. Next, we take the number 57,833,891 and divide it by 2:
57,833,891 ÷ 2 = 28,916,945.5
If the quotient is a whole number, then 2 and 28,916,945.5 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 | 57,833,891 | |
| -1 | -57,833,891 |
Now, we try dividing 57,833,891 by 3:
57,833,891 ÷ 3 = 19,277,963.6667
If the quotient is a whole number, then 3 and 19,277,963.6667 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 | 57,833,891 | |
| -1 | -57,833,891 |
Let's try dividing by 4:
57,833,891 ÷ 4 = 14,458,472.75
If the quotient is a whole number, then 4 and 14,458,472.75 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 | 57,833,891 | |
| -1 | 57,833,891 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 89 | 437 | 1,487 | 1,691 | 2,047 | 28,253 | 34,201 | 38,893 | 132,343 | 649,819 | 2,514,517 | 3,043,889 | 57,833,891 |
| -1 | -19 | -23 | -89 | -437 | -1,487 | -1,691 | -2,047 | -28,253 | -34,201 | -38,893 | -132,343 | -649,819 | -2,514,517 | -3,043,889 | -57,833,891 |
