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 93,775,405, 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 | 93,775,405 | |
| -1 | -93,775,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 93,775,405.
Example:
1 x 93,775,405 = 93,775,405
and
-1 x -93,775,405 = 93,775,405
Notice both answers equal 93,775,405
With that explanation out of the way, let's continue. Next, we take the number 93,775,405 and divide it by 2:
93,775,405 ÷ 2 = 46,887,702.5
If the quotient is a whole number, then 2 and 46,887,702.5 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 | 93,775,405 | |
| -1 | -93,775,405 |
Now, we try dividing 93,775,405 by 3:
93,775,405 ÷ 3 = 31,258,468.3333
If the quotient is a whole number, then 3 and 31,258,468.3333 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 | 93,775,405 | |
| -1 | -93,775,405 |
Let's try dividing by 4:
93,775,405 ÷ 4 = 23,443,851.25
If the quotient is a whole number, then 4 and 23,443,851.25 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 | 93,775,405 | |
| -1 | 93,775,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 205 | 619 | 739 | 3,095 | 3,695 | 25,379 | 30,299 | 126,895 | 151,495 | 457,441 | 2,287,205 | 18,755,081 | 93,775,405 |
| -1 | -5 | -41 | -205 | -619 | -739 | -3,095 | -3,695 | -25,379 | -30,299 | -126,895 | -151,495 | -457,441 | -2,287,205 | -18,755,081 | -93,775,405 |
