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 57,617,443, 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 | 57,617,443 | |
| -1 | -57,617,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,617,443.
Example:
1 x 57,617,443 = 57,617,443
and
-1 x -57,617,443 = 57,617,443
Notice both answers equal 57,617,443
With that explanation out of the way, let's continue. Next, we take the number 57,617,443 and divide it by 2:
57,617,443 ÷ 2 = 28,808,721.5
If the quotient is a whole number, then 2 and 28,808,721.5 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 | 57,617,443 | |
| -1 | -57,617,443 |
Now, we try dividing 57,617,443 by 3:
57,617,443 ÷ 3 = 19,205,814.3333
If the quotient is a whole number, then 3 and 19,205,814.3333 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 | 57,617,443 | |
| -1 | -57,617,443 |
Let's try dividing by 4:
57,617,443 ÷ 4 = 14,404,360.75
If the quotient is a whole number, then 4 and 14,404,360.75 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 | 57,617,443 | |
| -1 | 57,617,443 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 89 | 247 | 1,157 | 1,691 | 2,621 | 21,983 | 34,073 | 49,799 | 233,269 | 647,387 | 3,032,497 | 4,432,111 | 57,617,443 |
| -1 | -13 | -19 | -89 | -247 | -1,157 | -1,691 | -2,621 | -21,983 | -34,073 | -49,799 | -233,269 | -647,387 | -3,032,497 | -4,432,111 | -57,617,443 |
