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 276,647,459, 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 | 276,647,459 | |
| -1 | -276,647,459 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 276,647,459.
Example:
1 x 276,647,459 = 276,647,459
and
-1 x -276,647,459 = 276,647,459
Notice both answers equal 276,647,459
With that explanation out of the way, let's continue. Next, we take the number 276,647,459 and divide it by 2:
276,647,459 ÷ 2 = 138,323,729.5
If the quotient is a whole number, then 2 and 138,323,729.5 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 | 276,647,459 | |
| -1 | -276,647,459 |
Now, we try dividing 276,647,459 by 3:
276,647,459 ÷ 3 = 92,215,819.6667
If the quotient is a whole number, then 3 and 92,215,819.6667 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 | 276,647,459 | |
| -1 | -276,647,459 |
Let's try dividing by 4:
276,647,459 ÷ 4 = 69,161,864.75
If the quotient is a whole number, then 4 and 69,161,864.75 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 | 276,647,459 | |
| -1 | 276,647,459 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 181 | 451 | 1,991 | 3,389 | 7,421 | 37,279 | 81,631 | 138,949 | 613,409 | 1,528,439 | 6,747,499 | 25,149,769 | 276,647,459 |
| -1 | -11 | -41 | -181 | -451 | -1,991 | -3,389 | -7,421 | -37,279 | -81,631 | -138,949 | -613,409 | -1,528,439 | -6,747,499 | -25,149,769 | -276,647,459 |
