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 27,183,955, 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 | 27,183,955 | |
| -1 | -27,183,955 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,183,955.
Example:
1 x 27,183,955 = 27,183,955
and
-1 x -27,183,955 = 27,183,955
Notice both answers equal 27,183,955
With that explanation out of the way, let's continue. Next, we take the number 27,183,955 and divide it by 2:
27,183,955 ÷ 2 = 13,591,977.5
If the quotient is a whole number, then 2 and 13,591,977.5 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 | 27,183,955 | |
| -1 | -27,183,955 |
Now, we try dividing 27,183,955 by 3:
27,183,955 ÷ 3 = 9,061,318.3333
If the quotient is a whole number, then 3 and 9,061,318.3333 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 | 27,183,955 | |
| -1 | -27,183,955 |
Let's try dividing by 4:
27,183,955 ÷ 4 = 6,795,988.75
If the quotient is a whole number, then 4 and 6,795,988.75 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 | 27,183,955 | |
| -1 | 27,183,955 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 59 | 215 | 295 | 2,143 | 2,537 | 10,715 | 12,685 | 92,149 | 126,437 | 460,745 | 632,185 | 5,436,791 | 27,183,955 |
| -1 | -5 | -43 | -59 | -215 | -295 | -2,143 | -2,537 | -10,715 | -12,685 | -92,149 | -126,437 | -460,745 | -632,185 | -5,436,791 | -27,183,955 |
