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 35,786,309, 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 | 35,786,309 | |
| -1 | -35,786,309 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 35,786,309.
Example:
1 x 35,786,309 = 35,786,309
and
-1 x -35,786,309 = 35,786,309
Notice both answers equal 35,786,309
With that explanation out of the way, let's continue. Next, we take the number 35,786,309 and divide it by 2:
35,786,309 ÷ 2 = 17,893,154.5
If the quotient is a whole number, then 2 and 17,893,154.5 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 | 35,786,309 | |
| -1 | -35,786,309 |
Now, we try dividing 35,786,309 by 3:
35,786,309 ÷ 3 = 11,928,769.6667
If the quotient is a whole number, then 3 and 11,928,769.6667 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 | 35,786,309 | |
| -1 | -35,786,309 |
Let's try dividing by 4:
35,786,309 ÷ 4 = 8,946,577.25
If the quotient is a whole number, then 4 and 8,946,577.25 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 | 35,786,309 | |
| -1 | 35,786,309 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 113 | 221 | 1,433 | 1,469 | 1,921 | 18,629 | 24,361 | 24,973 | 161,929 | 316,693 | 2,105,077 | 2,752,793 | 35,786,309 |
| -1 | -13 | -17 | -113 | -221 | -1,433 | -1,469 | -1,921 | -18,629 | -24,361 | -24,973 | -161,929 | -316,693 | -2,105,077 | -2,752,793 | -35,786,309 |
