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 10,105,775, 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 | 10,105,775 | |
| -1 | -10,105,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,105,775.
Example:
1 x 10,105,775 = 10,105,775
and
-1 x -10,105,775 = 10,105,775
Notice both answers equal 10,105,775
With that explanation out of the way, let's continue. Next, we take the number 10,105,775 and divide it by 2:
10,105,775 ÷ 2 = 5,052,887.5
If the quotient is a whole number, then 2 and 5,052,887.5 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 | 10,105,775 | |
| -1 | -10,105,775 |
Now, we try dividing 10,105,775 by 3:
10,105,775 ÷ 3 = 3,368,591.6667
If the quotient is a whole number, then 3 and 3,368,591.6667 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 | 10,105,775 | |
| -1 | -10,105,775 |
Let's try dividing by 4:
10,105,775 ÷ 4 = 2,526,443.75
If the quotient is a whole number, then 4 and 2,526,443.75 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 | 10,105,775 | |
| -1 | 10,105,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 53 | 145 | 263 | 265 | 725 | 1,315 | 1,325 | 1,537 | 6,575 | 7,627 | 7,685 | 13,939 | 38,135 | 38,425 | 69,695 | 190,675 | 348,475 | 404,231 | 2,021,155 | 10,105,775 |
| -1 | -5 | -25 | -29 | -53 | -145 | -263 | -265 | -725 | -1,315 | -1,325 | -1,537 | -6,575 | -7,627 | -7,685 | -13,939 | -38,135 | -38,425 | -69,695 | -190,675 | -348,475 | -404,231 | -2,021,155 | -10,105,775 |
