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 8,636,243, 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 | 8,636,243 | |
| -1 | -8,636,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,636,243.
Example:
1 x 8,636,243 = 8,636,243
and
-1 x -8,636,243 = 8,636,243
Notice both answers equal 8,636,243
With that explanation out of the way, let's continue. Next, we take the number 8,636,243 and divide it by 2:
8,636,243 ÷ 2 = 4,318,121.5
If the quotient is a whole number, then 2 and 4,318,121.5 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 | 8,636,243 | |
| -1 | -8,636,243 |
Now, we try dividing 8,636,243 by 3:
8,636,243 ÷ 3 = 2,878,747.6667
If the quotient is a whole number, then 3 and 2,878,747.6667 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 | 8,636,243 | |
| -1 | -8,636,243 |
Let's try dividing by 4:
8,636,243 ÷ 4 = 2,159,060.75
If the quotient is a whole number, then 4 and 2,159,060.75 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 | 8,636,243 | |
| -1 | 8,636,243 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 59 | 77 | 413 | 649 | 1,901 | 4,543 | 13,307 | 20,911 | 112,159 | 146,377 | 785,113 | 1,233,749 | 8,636,243 |
| -1 | -7 | -11 | -59 | -77 | -413 | -649 | -1,901 | -4,543 | -13,307 | -20,911 | -112,159 | -146,377 | -785,113 | -1,233,749 | -8,636,243 |
