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 103,055,797, 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 | 103,055,797 | |
| -1 | -103,055,797 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,055,797.
Example:
1 x 103,055,797 = 103,055,797
and
-1 x -103,055,797 = 103,055,797
Notice both answers equal 103,055,797
With that explanation out of the way, let's continue. Next, we take the number 103,055,797 and divide it by 2:
103,055,797 ÷ 2 = 51,527,898.5
If the quotient is a whole number, then 2 and 51,527,898.5 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 | 103,055,797 | |
| -1 | -103,055,797 |
Now, we try dividing 103,055,797 by 3:
103,055,797 ÷ 3 = 34,351,932.3333
If the quotient is a whole number, then 3 and 34,351,932.3333 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 | 103,055,797 | |
| -1 | -103,055,797 |
Let's try dividing by 4:
103,055,797 ÷ 4 = 25,763,949.25
If the quotient is a whole number, then 4 and 25,763,949.25 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 | 103,055,797 | |
| -1 | 103,055,797 |
If you did it right, you will end up with this table:
| 1 | 13 | 53 | 373 | 401 | 689 | 4,849 | 5,213 | 19,769 | 21,253 | 149,573 | 256,997 | 276,289 | 1,944,449 | 7,927,369 | 103,055,797 |
| -1 | -13 | -53 | -373 | -401 | -689 | -4,849 | -5,213 | -19,769 | -21,253 | -149,573 | -256,997 | -276,289 | -1,944,449 | -7,927,369 | -103,055,797 |
