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 254,246,335, 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 | 254,246,335 | |
| -1 | -254,246,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 254,246,335.
Example:
1 x 254,246,335 = 254,246,335
and
-1 x -254,246,335 = 254,246,335
Notice both answers equal 254,246,335
With that explanation out of the way, let's continue. Next, we take the number 254,246,335 and divide it by 2:
254,246,335 ÷ 2 = 127,123,167.5
If the quotient is a whole number, then 2 and 127,123,167.5 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 | 254,246,335 | |
| -1 | -254,246,335 |
Now, we try dividing 254,246,335 by 3:
254,246,335 ÷ 3 = 84,748,778.3333
If the quotient is a whole number, then 3 and 84,748,778.3333 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 | 254,246,335 | |
| -1 | -254,246,335 |
Let's try dividing by 4:
254,246,335 ÷ 4 = 63,561,583.75
If the quotient is a whole number, then 4 and 63,561,583.75 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 | 254,246,335 | |
| -1 | 254,246,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 250,489 | 1,252,445 | 1,753,423 | 7,264,181 | 8,767,115 | 36,320,905 | 50,849,267 | 254,246,335 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -250,489 | -1,252,445 | -1,753,423 | -7,264,181 | -8,767,115 | -36,320,905 | -50,849,267 | -254,246,335 |
