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 27,755,465, 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 | 27,755,465 | |
| -1 | -27,755,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,755,465.
Example:
1 x 27,755,465 = 27,755,465
and
-1 x -27,755,465 = 27,755,465
Notice both answers equal 27,755,465
With that explanation out of the way, let's continue. Next, we take the number 27,755,465 and divide it by 2:
27,755,465 ÷ 2 = 13,877,732.5
If the quotient is a whole number, then 2 and 13,877,732.5 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 | 27,755,465 | |
| -1 | -27,755,465 |
Now, we try dividing 27,755,465 by 3:
27,755,465 ÷ 3 = 9,251,821.6667
If the quotient is a whole number, then 3 and 9,251,821.6667 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 | 27,755,465 | |
| -1 | -27,755,465 |
Let's try dividing by 4:
27,755,465 ÷ 4 = 6,938,866.25
If the quotient is a whole number, then 4 and 6,938,866.25 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 | 27,755,465 | |
| -1 | 27,755,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 79 | 145 | 395 | 2,291 | 2,423 | 11,455 | 12,115 | 70,267 | 191,417 | 351,335 | 957,085 | 5,551,093 | 27,755,465 |
| -1 | -5 | -29 | -79 | -145 | -395 | -2,291 | -2,423 | -11,455 | -12,115 | -70,267 | -191,417 | -351,335 | -957,085 | -5,551,093 | -27,755,465 |
