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 302,554,135, 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 | 302,554,135 | |
| -1 | -302,554,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,554,135.
Example:
1 x 302,554,135 = 302,554,135
and
-1 x -302,554,135 = 302,554,135
Notice both answers equal 302,554,135
With that explanation out of the way, let's continue. Next, we take the number 302,554,135 and divide it by 2:
302,554,135 ÷ 2 = 151,277,067.5
If the quotient is a whole number, then 2 and 151,277,067.5 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 | 302,554,135 | |
| -1 | -302,554,135 |
Now, we try dividing 302,554,135 by 3:
302,554,135 ÷ 3 = 100,851,378.3333
If the quotient is a whole number, then 3 and 100,851,378.3333 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 | 302,554,135 | |
| -1 | -302,554,135 |
Let's try dividing by 4:
302,554,135 ÷ 4 = 75,638,533.75
If the quotient is a whole number, then 4 and 75,638,533.75 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 | 302,554,135 | |
| -1 | 302,554,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 223 | 1,115 | 2,899 | 14,495 | 20,873 | 104,365 | 271,349 | 1,356,745 | 4,654,679 | 23,273,395 | 60,510,827 | 302,554,135 |
| -1 | -5 | -13 | -65 | -223 | -1,115 | -2,899 | -14,495 | -20,873 | -104,365 | -271,349 | -1,356,745 | -4,654,679 | -23,273,395 | -60,510,827 | -302,554,135 |
