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 57,874,327, 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 | 57,874,327 | |
| -1 | -57,874,327 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,874,327.
Example:
1 x 57,874,327 = 57,874,327
and
-1 x -57,874,327 = 57,874,327
Notice both answers equal 57,874,327
With that explanation out of the way, let's continue. Next, we take the number 57,874,327 and divide it by 2:
57,874,327 ÷ 2 = 28,937,163.5
If the quotient is a whole number, then 2 and 28,937,163.5 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 | 57,874,327 | |
| -1 | -57,874,327 |
Now, we try dividing 57,874,327 by 3:
57,874,327 ÷ 3 = 19,291,442.3333
If the quotient is a whole number, then 3 and 19,291,442.3333 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 | 57,874,327 | |
| -1 | -57,874,327 |
Let's try dividing by 4:
57,874,327 ÷ 4 = 14,468,581.75
If the quotient is a whole number, then 4 and 14,468,581.75 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 | 57,874,327 | |
| -1 | 57,874,327 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 73 | 259 | 511 | 2,701 | 3,061 | 18,907 | 21,427 | 113,257 | 223,453 | 792,799 | 1,564,171 | 8,267,761 | 57,874,327 |
| -1 | -7 | -37 | -73 | -259 | -511 | -2,701 | -3,061 | -18,907 | -21,427 | -113,257 | -223,453 | -792,799 | -1,564,171 | -8,267,761 | -57,874,327 |
