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 27,444,137, 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 | 27,444,137 | |
| -1 | -27,444,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,444,137.
Example:
1 x 27,444,137 = 27,444,137
and
-1 x -27,444,137 = 27,444,137
Notice both answers equal 27,444,137
With that explanation out of the way, let's continue. Next, we take the number 27,444,137 and divide it by 2:
27,444,137 ÷ 2 = 13,722,068.5
If the quotient is a whole number, then 2 and 13,722,068.5 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 | 27,444,137 | |
| -1 | -27,444,137 |
Now, we try dividing 27,444,137 by 3:
27,444,137 ÷ 3 = 9,148,045.6667
If the quotient is a whole number, then 3 and 9,148,045.6667 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 | 27,444,137 | |
| -1 | -27,444,137 |
Let's try dividing by 4:
27,444,137 ÷ 4 = 6,861,034.25
If the quotient is a whole number, then 4 and 6,861,034.25 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 | 27,444,137 | |
| -1 | 27,444,137 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 211 | 1,093 | 1,477 | 3,587 | 7,651 | 18,581 | 25,109 | 130,067 | 230,623 | 1,614,361 | 3,920,591 | 27,444,137 |
| -1 | -7 | -17 | -119 | -211 | -1,093 | -1,477 | -3,587 | -7,651 | -18,581 | -25,109 | -130,067 | -230,623 | -1,614,361 | -3,920,591 | -27,444,137 |
