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 27,209,345, 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 | 27,209,345 | |
| -1 | -27,209,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,209,345.
Example:
1 x 27,209,345 = 27,209,345
and
-1 x -27,209,345 = 27,209,345
Notice both answers equal 27,209,345
With that explanation out of the way, let's continue. Next, we take the number 27,209,345 and divide it by 2:
27,209,345 ÷ 2 = 13,604,672.5
If the quotient is a whole number, then 2 and 13,604,672.5 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 | 27,209,345 | |
| -1 | -27,209,345 |
Now, we try dividing 27,209,345 by 3:
27,209,345 ÷ 3 = 9,069,781.6667
If the quotient is a whole number, then 3 and 9,069,781.6667 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 | 27,209,345 | |
| -1 | -27,209,345 |
Let's try dividing by 4:
27,209,345 ÷ 4 = 6,802,336.25
If the quotient is a whole number, then 4 and 6,802,336.25 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 | 27,209,345 | |
| -1 | 27,209,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 223 | 1,061 | 1,115 | 5,129 | 5,305 | 24,403 | 25,645 | 122,015 | 236,603 | 1,183,015 | 5,441,869 | 27,209,345 |
| -1 | -5 | -23 | -115 | -223 | -1,061 | -1,115 | -5,129 | -5,305 | -24,403 | -25,645 | -122,015 | -236,603 | -1,183,015 | -5,441,869 | -27,209,345 |
