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 103,644,013, 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 | 103,644,013 | |
| -1 | -103,644,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,644,013.
Example:
1 x 103,644,013 = 103,644,013
and
-1 x -103,644,013 = 103,644,013
Notice both answers equal 103,644,013
With that explanation out of the way, let's continue. Next, we take the number 103,644,013 and divide it by 2:
103,644,013 ÷ 2 = 51,822,006.5
If the quotient is a whole number, then 2 and 51,822,006.5 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 | 103,644,013 | |
| -1 | -103,644,013 |
Now, we try dividing 103,644,013 by 3:
103,644,013 ÷ 3 = 34,548,004.3333
If the quotient is a whole number, then 3 and 34,548,004.3333 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 | 103,644,013 | |
| -1 | -103,644,013 |
Let's try dividing by 4:
103,644,013 ÷ 4 = 25,911,003.25
If the quotient is a whole number, then 4 and 25,911,003.25 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 | 103,644,013 | |
| -1 | 103,644,013 |
If you did it right, you will end up with this table:
| 1 | 11 | 73 | 337 | 383 | 803 | 3,707 | 4,213 | 24,601 | 27,959 | 129,071 | 270,611 | 307,549 | 1,419,781 | 9,422,183 | 103,644,013 |
| -1 | -11 | -73 | -337 | -383 | -803 | -3,707 | -4,213 | -24,601 | -27,959 | -129,071 | -270,611 | -307,549 | -1,419,781 | -9,422,183 | -103,644,013 |
