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 109,005,347, 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 | 109,005,347 | |
| -1 | -109,005,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 109,005,347.
Example:
1 x 109,005,347 = 109,005,347
and
-1 x -109,005,347 = 109,005,347
Notice both answers equal 109,005,347
With that explanation out of the way, let's continue. Next, we take the number 109,005,347 and divide it by 2:
109,005,347 ÷ 2 = 54,502,673.5
If the quotient is a whole number, then 2 and 54,502,673.5 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 | 109,005,347 | |
| -1 | -109,005,347 |
Now, we try dividing 109,005,347 by 3:
109,005,347 ÷ 3 = 36,335,115.6667
If the quotient is a whole number, then 3 and 36,335,115.6667 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 | 109,005,347 | |
| -1 | -109,005,347 |
Let's try dividing by 4:
109,005,347 ÷ 4 = 27,251,336.75
If the quotient is a whole number, then 4 and 27,251,336.75 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 | 109,005,347 | |
| -1 | 109,005,347 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 263 | 451 | 919 | 2,893 | 10,109 | 10,783 | 37,679 | 118,613 | 241,697 | 414,469 | 2,658,667 | 9,909,577 | 109,005,347 |
| -1 | -11 | -41 | -263 | -451 | -919 | -2,893 | -10,109 | -10,783 | -37,679 | -118,613 | -241,697 | -414,469 | -2,658,667 | -9,909,577 | -109,005,347 |
