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 27,136,285, 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 | 27,136,285 | |
| -1 | -27,136,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,136,285.
Example:
1 x 27,136,285 = 27,136,285
and
-1 x -27,136,285 = 27,136,285
Notice both answers equal 27,136,285
With that explanation out of the way, let's continue. Next, we take the number 27,136,285 and divide it by 2:
27,136,285 ÷ 2 = 13,568,142.5
If the quotient is a whole number, then 2 and 13,568,142.5 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 | 27,136,285 | |
| -1 | -27,136,285 |
Now, we try dividing 27,136,285 by 3:
27,136,285 ÷ 3 = 9,045,428.3333
If the quotient is a whole number, then 3 and 9,045,428.3333 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 | 27,136,285 | |
| -1 | -27,136,285 |
Let's try dividing by 4:
27,136,285 ÷ 4 = 6,784,071.25
If the quotient is a whole number, then 4 and 6,784,071.25 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 | 27,136,285 | |
| -1 | 27,136,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 521 | 947 | 2,605 | 4,735 | 5,731 | 10,417 | 28,655 | 52,085 | 493,387 | 2,466,935 | 5,427,257 | 27,136,285 |
| -1 | -5 | -11 | -55 | -521 | -947 | -2,605 | -4,735 | -5,731 | -10,417 | -28,655 | -52,085 | -493,387 | -2,466,935 | -5,427,257 | -27,136,285 |
