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 109,135,645, 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 | 109,135,645 | |
| -1 | -109,135,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 109,135,645.
Example:
1 x 109,135,645 = 109,135,645
and
-1 x -109,135,645 = 109,135,645
Notice both answers equal 109,135,645
With that explanation out of the way, let's continue. Next, we take the number 109,135,645 and divide it by 2:
109,135,645 ÷ 2 = 54,567,822.5
If the quotient is a whole number, then 2 and 54,567,822.5 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 | 109,135,645 | |
| -1 | -109,135,645 |
Now, we try dividing 109,135,645 by 3:
109,135,645 ÷ 3 = 36,378,548.3333
If the quotient is a whole number, then 3 and 36,378,548.3333 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 | 109,135,645 | |
| -1 | -109,135,645 |
Let's try dividing by 4:
109,135,645 ÷ 4 = 27,283,911.25
If the quotient is a whole number, then 4 and 27,283,911.25 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 | 109,135,645 | |
| -1 | 109,135,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 47 | 205 | 235 | 241 | 1,205 | 1,927 | 2,209 | 9,635 | 9,881 | 11,045 | 11,327 | 49,405 | 56,635 | 90,569 | 452,845 | 464,407 | 532,369 | 2,322,035 | 2,661,845 | 21,827,129 | 109,135,645 |
| -1 | -5 | -41 | -47 | -205 | -235 | -241 | -1,205 | -1,927 | -2,209 | -9,635 | -9,881 | -11,045 | -11,327 | -49,405 | -56,635 | -90,569 | -452,845 | -464,407 | -532,369 | -2,322,035 | -2,661,845 | -21,827,129 | -109,135,645 |
