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 10,363,685, 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 | 10,363,685 | |
| -1 | -10,363,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,363,685.
Example:
1 x 10,363,685 = 10,363,685
and
-1 x -10,363,685 = 10,363,685
Notice both answers equal 10,363,685
With that explanation out of the way, let's continue. Next, we take the number 10,363,685 and divide it by 2:
10,363,685 ÷ 2 = 5,181,842.5
If the quotient is a whole number, then 2 and 5,181,842.5 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 | 10,363,685 | |
| -1 | -10,363,685 |
Now, we try dividing 10,363,685 by 3:
10,363,685 ÷ 3 = 3,454,561.6667
If the quotient is a whole number, then 3 and 3,454,561.6667 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 | 10,363,685 | |
| -1 | -10,363,685 |
Let's try dividing by 4:
10,363,685 ÷ 4 = 2,590,921.25
If the quotient is a whole number, then 4 and 2,590,921.25 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 | 10,363,685 | |
| -1 | 10,363,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 227 | 397 | 1,135 | 1,985 | 5,221 | 9,131 | 26,105 | 45,655 | 90,119 | 450,595 | 2,072,737 | 10,363,685 |
| -1 | -5 | -23 | -115 | -227 | -397 | -1,135 | -1,985 | -5,221 | -9,131 | -26,105 | -45,655 | -90,119 | -450,595 | -2,072,737 | -10,363,685 |
