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 27,358,799, 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 | 27,358,799 | |
| -1 | -27,358,799 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,358,799.
Example:
1 x 27,358,799 = 27,358,799
and
-1 x -27,358,799 = 27,358,799
Notice both answers equal 27,358,799
With that explanation out of the way, let's continue. Next, we take the number 27,358,799 and divide it by 2:
27,358,799 ÷ 2 = 13,679,399.5
If the quotient is a whole number, then 2 and 13,679,399.5 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 | 27,358,799 | |
| -1 | -27,358,799 |
Now, we try dividing 27,358,799 by 3:
27,358,799 ÷ 3 = 9,119,599.6667
If the quotient is a whole number, then 3 and 9,119,599.6667 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 | 27,358,799 | |
| -1 | -27,358,799 |
Let's try dividing by 4:
27,358,799 ÷ 4 = 6,839,699.75
If the quotient is a whole number, then 4 and 6,839,699.75 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 | 27,358,799 | |
| -1 | 27,358,799 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 37 | 299 | 481 | 851 | 2,473 | 11,063 | 32,149 | 56,879 | 91,501 | 739,427 | 1,189,513 | 2,104,523 | 27,358,799 |
| -1 | -13 | -23 | -37 | -299 | -481 | -851 | -2,473 | -11,063 | -32,149 | -56,879 | -91,501 | -739,427 | -1,189,513 | -2,104,523 | -27,358,799 |
