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 10,631,405, 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 | 10,631,405 | |
| -1 | -10,631,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,631,405.
Example:
1 x 10,631,405 = 10,631,405
and
-1 x -10,631,405 = 10,631,405
Notice both answers equal 10,631,405
With that explanation out of the way, let's continue. Next, we take the number 10,631,405 and divide it by 2:
10,631,405 ÷ 2 = 5,315,702.5
If the quotient is a whole number, then 2 and 5,315,702.5 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 | 10,631,405 | |
| -1 | -10,631,405 |
Now, we try dividing 10,631,405 by 3:
10,631,405 ÷ 3 = 3,543,801.6667
If the quotient is a whole number, then 3 and 3,543,801.6667 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 | 10,631,405 | |
| -1 | -10,631,405 |
Let's try dividing by 4:
10,631,405 ÷ 4 = 2,657,851.25
If the quotient is a whole number, then 4 and 2,657,851.25 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 | 10,631,405 | |
| -1 | 10,631,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 193 | 479 | 965 | 2,395 | 4,439 | 11,017 | 22,195 | 55,085 | 92,447 | 462,235 | 2,126,281 | 10,631,405 |
| -1 | -5 | -23 | -115 | -193 | -479 | -965 | -2,395 | -4,439 | -11,017 | -22,195 | -55,085 | -92,447 | -462,235 | -2,126,281 | -10,631,405 |
