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 103,643,939, 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 | 103,643,939 | |
| -1 | -103,643,939 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,643,939.
Example:
1 x 103,643,939 = 103,643,939
and
-1 x -103,643,939 = 103,643,939
Notice both answers equal 103,643,939
With that explanation out of the way, let's continue. Next, we take the number 103,643,939 and divide it by 2:
103,643,939 ÷ 2 = 51,821,969.5
If the quotient is a whole number, then 2 and 51,821,969.5 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 | 103,643,939 | |
| -1 | -103,643,939 |
Now, we try dividing 103,643,939 by 3:
103,643,939 ÷ 3 = 34,547,979.6667
If the quotient is a whole number, then 3 and 34,547,979.6667 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 | 103,643,939 | |
| -1 | -103,643,939 |
Let's try dividing by 4:
103,643,939 ÷ 4 = 25,910,984.75
If the quotient is a whole number, then 4 and 25,910,984.75 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 | 103,643,939 | |
| -1 | 103,643,939 |
If you did it right, you will end up with this table:
| 1 | 7 | 113 | 283 | 463 | 791 | 1,981 | 3,241 | 31,979 | 52,319 | 131,029 | 223,853 | 366,233 | 917,203 | 14,806,277 | 103,643,939 |
| -1 | -7 | -113 | -283 | -463 | -791 | -1,981 | -3,241 | -31,979 | -52,319 | -131,029 | -223,853 | -366,233 | -917,203 | -14,806,277 | -103,643,939 |
