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 254,048,125, 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 | 254,048,125 | |
| -1 | -254,048,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 254,048,125.
Example:
1 x 254,048,125 = 254,048,125
and
-1 x -254,048,125 = 254,048,125
Notice both answers equal 254,048,125
With that explanation out of the way, let's continue. Next, we take the number 254,048,125 and divide it by 2:
254,048,125 ÷ 2 = 127,024,062.5
If the quotient is a whole number, then 2 and 127,024,062.5 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 | 254,048,125 | |
| -1 | -254,048,125 |
Now, we try dividing 254,048,125 by 3:
254,048,125 ÷ 3 = 84,682,708.3333
If the quotient is a whole number, then 3 and 84,682,708.3333 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 | 254,048,125 | |
| -1 | -254,048,125 |
Let's try dividing by 4:
254,048,125 ÷ 4 = 63,512,031.25
If the quotient is a whole number, then 4 and 63,512,031.25 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 | 254,048,125 | |
| -1 | 254,048,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 311 | 625 | 1,307 | 1,555 | 6,535 | 7,775 | 32,675 | 38,875 | 163,375 | 194,375 | 406,477 | 816,875 | 2,032,385 | 10,161,925 | 50,809,625 | 254,048,125 |
| -1 | -5 | -25 | -125 | -311 | -625 | -1,307 | -1,555 | -6,535 | -7,775 | -32,675 | -38,875 | -163,375 | -194,375 | -406,477 | -816,875 | -2,032,385 | -10,161,925 | -50,809,625 | -254,048,125 |
