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 103,439,147, 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 | 103,439,147 | |
| -1 | -103,439,147 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,439,147.
Example:
1 x 103,439,147 = 103,439,147
and
-1 x -103,439,147 = 103,439,147
Notice both answers equal 103,439,147
With that explanation out of the way, let's continue. Next, we take the number 103,439,147 and divide it by 2:
103,439,147 ÷ 2 = 51,719,573.5
If the quotient is a whole number, then 2 and 51,719,573.5 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 | 103,439,147 | |
| -1 | -103,439,147 |
Now, we try dividing 103,439,147 by 3:
103,439,147 ÷ 3 = 34,479,715.6667
If the quotient is a whole number, then 3 and 34,479,715.6667 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 | 103,439,147 | |
| -1 | -103,439,147 |
Let's try dividing by 4:
103,439,147 ÷ 4 = 25,859,786.75
If the quotient is a whole number, then 4 and 25,859,786.75 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 | 103,439,147 | |
| -1 | 103,439,147 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 107 | 109 | 181 | 749 | 763 | 1,267 | 5,243 | 5,341 | 8,869 | 11,663 | 19,367 | 19,729 | 81,641 | 135,569 | 138,103 | 571,487 | 948,983 | 966,721 | 2,111,003 | 14,777,021 | 103,439,147 |
| -1 | -7 | -49 | -107 | -109 | -181 | -749 | -763 | -1,267 | -5,243 | -5,341 | -8,869 | -11,663 | -19,367 | -19,729 | -81,641 | -135,569 | -138,103 | -571,487 | -948,983 | -966,721 | -2,111,003 | -14,777,021 | -103,439,147 |
