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 57,193,015, 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 | 57,193,015 | |
| -1 | -57,193,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,193,015.
Example:
1 x 57,193,015 = 57,193,015
and
-1 x -57,193,015 = 57,193,015
Notice both answers equal 57,193,015
With that explanation out of the way, let's continue. Next, we take the number 57,193,015 and divide it by 2:
57,193,015 ÷ 2 = 28,596,507.5
If the quotient is a whole number, then 2 and 28,596,507.5 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 | 57,193,015 | |
| -1 | -57,193,015 |
Now, we try dividing 57,193,015 by 3:
57,193,015 ÷ 3 = 19,064,338.3333
If the quotient is a whole number, then 3 and 19,064,338.3333 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 | 57,193,015 | |
| -1 | -57,193,015 |
Let's try dividing by 4:
57,193,015 ÷ 4 = 14,298,253.75
If the quotient is a whole number, then 4 and 14,298,253.75 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 | 57,193,015 | |
| -1 | 57,193,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 61,169 | 305,845 | 672,859 | 1,039,873 | 3,364,295 | 5,199,365 | 11,438,603 | 57,193,015 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -61,169 | -305,845 | -672,859 | -1,039,873 | -3,364,295 | -5,199,365 | -11,438,603 | -57,193,015 |
