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 302,403,115, 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 | 302,403,115 | |
| -1 | -302,403,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,403,115.
Example:
1 x 302,403,115 = 302,403,115
and
-1 x -302,403,115 = 302,403,115
Notice both answers equal 302,403,115
With that explanation out of the way, let's continue. Next, we take the number 302,403,115 and divide it by 2:
302,403,115 ÷ 2 = 151,201,557.5
If the quotient is a whole number, then 2 and 151,201,557.5 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 | 302,403,115 | |
| -1 | -302,403,115 |
Now, we try dividing 302,403,115 by 3:
302,403,115 ÷ 3 = 100,801,038.3333
If the quotient is a whole number, then 3 and 100,801,038.3333 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 | 302,403,115 | |
| -1 | -302,403,115 |
Let's try dividing by 4:
302,403,115 ÷ 4 = 75,600,778.75
If the quotient is a whole number, then 4 and 75,600,778.75 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 | 302,403,115 | |
| -1 | 302,403,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 239 | 1,195 | 1,673 | 8,365 | 36,151 | 180,755 | 253,057 | 1,265,285 | 8,640,089 | 43,200,445 | 60,480,623 | 302,403,115 |
| -1 | -5 | -7 | -35 | -239 | -1,195 | -1,673 | -8,365 | -36,151 | -180,755 | -253,057 | -1,265,285 | -8,640,089 | -43,200,445 | -60,480,623 | -302,403,115 |
