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 254,314,427, 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 | 254,314,427 | |
| -1 | -254,314,427 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 254,314,427.
Example:
1 x 254,314,427 = 254,314,427
and
-1 x -254,314,427 = 254,314,427
Notice both answers equal 254,314,427
With that explanation out of the way, let's continue. Next, we take the number 254,314,427 and divide it by 2:
254,314,427 ÷ 2 = 127,157,213.5
If the quotient is a whole number, then 2 and 127,157,213.5 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 | 254,314,427 | |
| -1 | -254,314,427 |
Now, we try dividing 254,314,427 by 3:
254,314,427 ÷ 3 = 84,771,475.6667
If the quotient is a whole number, then 3 and 84,771,475.6667 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 | 254,314,427 | |
| -1 | -254,314,427 |
Let's try dividing by 4:
254,314,427 ÷ 4 = 63,578,606.75
If the quotient is a whole number, then 4 and 63,578,606.75 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 | 254,314,427 | |
| -1 | 254,314,427 |
If you did it right, you will end up with this table:
| 1 | 23 | 29 | 43 | 667 | 989 | 1,247 | 8,867 | 28,681 | 203,941 | 257,143 | 381,281 | 5,914,289 | 8,769,463 | 11,057,149 | 254,314,427 |
| -1 | -23 | -29 | -43 | -667 | -989 | -1,247 | -8,867 | -28,681 | -203,941 | -257,143 | -381,281 | -5,914,289 | -8,769,463 | -11,057,149 | -254,314,427 |
