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 254,016,529, 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 | 254,016,529 | |
| -1 | -254,016,529 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 254,016,529.
Example:
1 x 254,016,529 = 254,016,529
and
-1 x -254,016,529 = 254,016,529
Notice both answers equal 254,016,529
With that explanation out of the way, let's continue. Next, we take the number 254,016,529 and divide it by 2:
254,016,529 ÷ 2 = 127,008,264.5
If the quotient is a whole number, then 2 and 127,008,264.5 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 | 254,016,529 | |
| -1 | -254,016,529 |
Now, we try dividing 254,016,529 by 3:
254,016,529 ÷ 3 = 84,672,176.3333
If the quotient is a whole number, then 3 and 84,672,176.3333 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 | 254,016,529 | |
| -1 | -254,016,529 |
Let's try dividing by 4:
254,016,529 ÷ 4 = 63,504,132.25
If the quotient is a whole number, then 4 and 63,504,132.25 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 | 254,016,529 | |
| -1 | 254,016,529 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 47 | 247 | 611 | 893 | 11,609 | 21,881 | 284,453 | 415,739 | 1,028,407 | 5,404,607 | 13,369,291 | 19,539,733 | 254,016,529 |
| -1 | -13 | -19 | -47 | -247 | -611 | -893 | -11,609 | -21,881 | -284,453 | -415,739 | -1,028,407 | -5,404,607 | -13,369,291 | -19,539,733 | -254,016,529 |
