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 27,481,435, 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 | 27,481,435 | |
| -1 | -27,481,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,481,435.
Example:
1 x 27,481,435 = 27,481,435
and
-1 x -27,481,435 = 27,481,435
Notice both answers equal 27,481,435
With that explanation out of the way, let's continue. Next, we take the number 27,481,435 and divide it by 2:
27,481,435 ÷ 2 = 13,740,717.5
If the quotient is a whole number, then 2 and 13,740,717.5 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 | 27,481,435 | |
| -1 | -27,481,435 |
Now, we try dividing 27,481,435 by 3:
27,481,435 ÷ 3 = 9,160,478.3333
If the quotient is a whole number, then 3 and 9,160,478.3333 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 | 27,481,435 | |
| -1 | -27,481,435 |
Let's try dividing by 4:
27,481,435 ÷ 4 = 6,870,358.75
If the quotient is a whole number, then 4 and 6,870,358.75 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 | 27,481,435 | |
| -1 | 27,481,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 85 | 115 | 391 | 1,955 | 14,057 | 70,285 | 238,969 | 323,311 | 1,194,845 | 1,616,555 | 5,496,287 | 27,481,435 |
| -1 | -5 | -17 | -23 | -85 | -115 | -391 | -1,955 | -14,057 | -70,285 | -238,969 | -323,311 | -1,194,845 | -1,616,555 | -5,496,287 | -27,481,435 |
