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 102,636,443, 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 | 102,636,443 | |
| -1 | -102,636,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,636,443.
Example:
1 x 102,636,443 = 102,636,443
and
-1 x -102,636,443 = 102,636,443
Notice both answers equal 102,636,443
With that explanation out of the way, let's continue. Next, we take the number 102,636,443 and divide it by 2:
102,636,443 ÷ 2 = 51,318,221.5
If the quotient is a whole number, then 2 and 51,318,221.5 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 | 102,636,443 | |
| -1 | -102,636,443 |
Now, we try dividing 102,636,443 by 3:
102,636,443 ÷ 3 = 34,212,147.6667
If the quotient is a whole number, then 3 and 34,212,147.6667 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 | 102,636,443 | |
| -1 | -102,636,443 |
Let's try dividing by 4:
102,636,443 ÷ 4 = 25,659,110.75
If the quotient is a whole number, then 4 and 25,659,110.75 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 | 102,636,443 | |
| -1 | 102,636,443 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 31 | 91 | 217 | 403 | 2,821 | 36,383 | 254,681 | 472,979 | 1,127,873 | 3,310,853 | 7,895,111 | 14,662,349 | 102,636,443 |
| -1 | -7 | -13 | -31 | -91 | -217 | -403 | -2,821 | -36,383 | -254,681 | -472,979 | -1,127,873 | -3,310,853 | -7,895,111 | -14,662,349 | -102,636,443 |
