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 27,365,155, 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 | 27,365,155 | |
| -1 | -27,365,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,365,155.
Example:
1 x 27,365,155 = 27,365,155
and
-1 x -27,365,155 = 27,365,155
Notice both answers equal 27,365,155
With that explanation out of the way, let's continue. Next, we take the number 27,365,155 and divide it by 2:
27,365,155 ÷ 2 = 13,682,577.5
If the quotient is a whole number, then 2 and 13,682,577.5 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 | 27,365,155 | |
| -1 | -27,365,155 |
Now, we try dividing 27,365,155 by 3:
27,365,155 ÷ 3 = 9,121,718.3333
If the quotient is a whole number, then 3 and 9,121,718.3333 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 | 27,365,155 | |
| -1 | -27,365,155 |
Let's try dividing by 4:
27,365,155 ÷ 4 = 6,841,288.75
If the quotient is a whole number, then 4 and 6,841,288.75 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 | 27,365,155 | |
| -1 | 27,365,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 97 | 485 | 1,649 | 3,319 | 8,245 | 16,595 | 56,423 | 282,115 | 321,943 | 1,609,715 | 5,473,031 | 27,365,155 |
| -1 | -5 | -17 | -85 | -97 | -485 | -1,649 | -3,319 | -8,245 | -16,595 | -56,423 | -282,115 | -321,943 | -1,609,715 | -5,473,031 | -27,365,155 |
