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 254,301,335, 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 | 254,301,335 | |
| -1 | -254,301,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 254,301,335.
Example:
1 x 254,301,335 = 254,301,335
and
-1 x -254,301,335 = 254,301,335
Notice both answers equal 254,301,335
With that explanation out of the way, let's continue. Next, we take the number 254,301,335 and divide it by 2:
254,301,335 ÷ 2 = 127,150,667.5
If the quotient is a whole number, then 2 and 127,150,667.5 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 | 254,301,335 | |
| -1 | -254,301,335 |
Now, we try dividing 254,301,335 by 3:
254,301,335 ÷ 3 = 84,767,111.6667
If the quotient is a whole number, then 3 and 84,767,111.6667 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 | 254,301,335 | |
| -1 | -254,301,335 |
Let's try dividing by 4:
254,301,335 ÷ 4 = 63,575,333.75
If the quotient is a whole number, then 4 and 63,575,333.75 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 | 254,301,335 | |
| -1 | 254,301,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 101 | 103 | 505 | 515 | 4,889 | 10,403 | 24,445 | 52,015 | 493,789 | 503,567 | 2,468,945 | 2,517,835 | 50,860,267 | 254,301,335 |
| -1 | -5 | -101 | -103 | -505 | -515 | -4,889 | -10,403 | -24,445 | -52,015 | -493,789 | -503,567 | -2,468,945 | -2,517,835 | -50,860,267 | -254,301,335 |
