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 27,673,565, 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 | 27,673,565 | |
| -1 | -27,673,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,673,565.
Example:
1 x 27,673,565 = 27,673,565
and
-1 x -27,673,565 = 27,673,565
Notice both answers equal 27,673,565
With that explanation out of the way, let's continue. Next, we take the number 27,673,565 and divide it by 2:
27,673,565 ÷ 2 = 13,836,782.5
If the quotient is a whole number, then 2 and 13,836,782.5 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 | 27,673,565 | |
| -1 | -27,673,565 |
Now, we try dividing 27,673,565 by 3:
27,673,565 ÷ 3 = 9,224,521.6667
If the quotient is a whole number, then 3 and 9,224,521.6667 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 | 27,673,565 | |
| -1 | -27,673,565 |
Let's try dividing by 4:
27,673,565 ÷ 4 = 6,918,391.25
If the quotient is a whole number, then 4 and 6,918,391.25 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 | 27,673,565 | |
| -1 | 27,673,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 61 | 205 | 305 | 2,213 | 2,501 | 11,065 | 12,505 | 90,733 | 134,993 | 453,665 | 674,965 | 5,534,713 | 27,673,565 |
| -1 | -5 | -41 | -61 | -205 | -305 | -2,213 | -2,501 | -11,065 | -12,505 | -90,733 | -134,993 | -453,665 | -674,965 | -5,534,713 | -27,673,565 |
