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 10,002,443, 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 | 10,002,443 | |
| -1 | -10,002,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,002,443.
Example:
1 x 10,002,443 = 10,002,443
and
-1 x -10,002,443 = 10,002,443
Notice both answers equal 10,002,443
With that explanation out of the way, let's continue. Next, we take the number 10,002,443 and divide it by 2:
10,002,443 ÷ 2 = 5,001,221.5
If the quotient is a whole number, then 2 and 5,001,221.5 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 | 10,002,443 | |
| -1 | -10,002,443 |
Now, we try dividing 10,002,443 by 3:
10,002,443 ÷ 3 = 3,334,147.6667
If the quotient is a whole number, then 3 and 3,334,147.6667 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 | 10,002,443 | |
| -1 | -10,002,443 |
Let's try dividing by 4:
10,002,443 ÷ 4 = 2,500,610.75
If the quotient is a whole number, then 4 and 2,500,610.75 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 | 10,002,443 | |
| -1 | 10,002,443 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 89 | 187 | 601 | 979 | 1,513 | 6,611 | 10,217 | 16,643 | 53,489 | 112,387 | 588,379 | 909,313 | 10,002,443 |
| -1 | -11 | -17 | -89 | -187 | -601 | -979 | -1,513 | -6,611 | -10,217 | -16,643 | -53,489 | -112,387 | -588,379 | -909,313 | -10,002,443 |
