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 105,425,099, 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 | 105,425,099 | |
| -1 | -105,425,099 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 105,425,099.
Example:
1 x 105,425,099 = 105,425,099
and
-1 x -105,425,099 = 105,425,099
Notice both answers equal 105,425,099
With that explanation out of the way, let's continue. Next, we take the number 105,425,099 and divide it by 2:
105,425,099 ÷ 2 = 52,712,549.5
If the quotient is a whole number, then 2 and 52,712,549.5 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 | 105,425,099 | |
| -1 | -105,425,099 |
Now, we try dividing 105,425,099 by 3:
105,425,099 ÷ 3 = 35,141,699.6667
If the quotient is a whole number, then 3 and 35,141,699.6667 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 | 105,425,099 | |
| -1 | -105,425,099 |
Let's try dividing by 4:
105,425,099 ÷ 4 = 26,356,274.75
If the quotient is a whole number, then 4 and 26,356,274.75 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 | 105,425,099 | |
| -1 | 105,425,099 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 149 | 481 | 1,471 | 1,937 | 5,513 | 19,123 | 54,427 | 71,669 | 219,179 | 707,551 | 2,849,327 | 8,109,623 | 105,425,099 |
| -1 | -13 | -37 | -149 | -481 | -1,471 | -1,937 | -5,513 | -19,123 | -54,427 | -71,669 | -219,179 | -707,551 | -2,849,327 | -8,109,623 | -105,425,099 |
