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 103,134,223, 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 | 103,134,223 | |
| -1 | -103,134,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,134,223.
Example:
1 x 103,134,223 = 103,134,223
and
-1 x -103,134,223 = 103,134,223
Notice both answers equal 103,134,223
With that explanation out of the way, let's continue. Next, we take the number 103,134,223 and divide it by 2:
103,134,223 ÷ 2 = 51,567,111.5
If the quotient is a whole number, then 2 and 51,567,111.5 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 | 103,134,223 | |
| -1 | -103,134,223 |
Now, we try dividing 103,134,223 by 3:
103,134,223 ÷ 3 = 34,378,074.3333
If the quotient is a whole number, then 3 and 34,378,074.3333 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 | 103,134,223 | |
| -1 | -103,134,223 |
Let's try dividing by 4:
103,134,223 ÷ 4 = 25,783,555.75
If the quotient is a whole number, then 4 and 25,783,555.75 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 | 103,134,223 | |
| -1 | 103,134,223 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 83 | 323 | 1,411 | 1,577 | 3,847 | 26,809 | 65,399 | 73,093 | 319,301 | 1,242,581 | 5,428,117 | 6,066,719 | 103,134,223 |
| -1 | -17 | -19 | -83 | -323 | -1,411 | -1,577 | -3,847 | -26,809 | -65,399 | -73,093 | -319,301 | -1,242,581 | -5,428,117 | -6,066,719 | -103,134,223 |
