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 27,675,541, 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 | 27,675,541 | |
| -1 | -27,675,541 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,675,541.
Example:
1 x 27,675,541 = 27,675,541
and
-1 x -27,675,541 = 27,675,541
Notice both answers equal 27,675,541
With that explanation out of the way, let's continue. Next, we take the number 27,675,541 and divide it by 2:
27,675,541 ÷ 2 = 13,837,770.5
If the quotient is a whole number, then 2 and 13,837,770.5 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 | 27,675,541 | |
| -1 | -27,675,541 |
Now, we try dividing 27,675,541 by 3:
27,675,541 ÷ 3 = 9,225,180.3333
If the quotient is a whole number, then 3 and 9,225,180.3333 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 | 27,675,541 | |
| -1 | -27,675,541 |
Let's try dividing by 4:
27,675,541 ÷ 4 = 6,918,885.25
If the quotient is a whole number, then 4 and 6,918,885.25 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 | 27,675,541 | |
| -1 | 27,675,541 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 73 | 493 | 769 | 1,241 | 2,117 | 13,073 | 22,301 | 35,989 | 56,137 | 379,117 | 954,329 | 1,627,973 | 27,675,541 |
| -1 | -17 | -29 | -73 | -493 | -769 | -1,241 | -2,117 | -13,073 | -22,301 | -35,989 | -56,137 | -379,117 | -954,329 | -1,627,973 | -27,675,541 |
