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 254,026,775, 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 | 254,026,775 | |
| -1 | -254,026,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 254,026,775.
Example:
1 x 254,026,775 = 254,026,775
and
-1 x -254,026,775 = 254,026,775
Notice both answers equal 254,026,775
With that explanation out of the way, let's continue. Next, we take the number 254,026,775 and divide it by 2:
254,026,775 ÷ 2 = 127,013,387.5
If the quotient is a whole number, then 2 and 127,013,387.5 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 | 254,026,775 | |
| -1 | -254,026,775 |
Now, we try dividing 254,026,775 by 3:
254,026,775 ÷ 3 = 84,675,591.6667
If the quotient is a whole number, then 3 and 84,675,591.6667 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 | 254,026,775 | |
| -1 | -254,026,775 |
Let's try dividing by 4:
254,026,775 ÷ 4 = 63,506,693.75
If the quotient is a whole number, then 4 and 63,506,693.75 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 | 254,026,775 | |
| -1 | 254,026,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 41 | 47 | 205 | 235 | 1,025 | 1,175 | 1,927 | 5,273 | 9,635 | 26,365 | 48,175 | 131,825 | 216,193 | 247,831 | 1,080,965 | 1,239,155 | 5,404,825 | 6,195,775 | 10,161,071 | 50,805,355 | 254,026,775 |
| -1 | -5 | -25 | -41 | -47 | -205 | -235 | -1,025 | -1,175 | -1,927 | -5,273 | -9,635 | -26,365 | -48,175 | -131,825 | -216,193 | -247,831 | -1,080,965 | -1,239,155 | -5,404,825 | -6,195,775 | -10,161,071 | -50,805,355 | -254,026,775 |
