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 302,300,995, 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 | 302,300,995 | |
| -1 | -302,300,995 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,300,995.
Example:
1 x 302,300,995 = 302,300,995
and
-1 x -302,300,995 = 302,300,995
Notice both answers equal 302,300,995
With that explanation out of the way, let's continue. Next, we take the number 302,300,995 and divide it by 2:
302,300,995 ÷ 2 = 151,150,497.5
If the quotient is a whole number, then 2 and 151,150,497.5 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 | 302,300,995 | |
| -1 | -302,300,995 |
Now, we try dividing 302,300,995 by 3:
302,300,995 ÷ 3 = 100,766,998.3333
If the quotient is a whole number, then 3 and 100,766,998.3333 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 | 302,300,995 | |
| -1 | -302,300,995 |
Let's try dividing by 4:
302,300,995 ÷ 4 = 75,575,248.75
If the quotient is a whole number, then 4 and 75,575,248.75 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 | 302,300,995 | |
| -1 | 302,300,995 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 41 | 155 | 205 | 1,271 | 6,355 | 47,569 | 237,845 | 1,474,639 | 1,950,329 | 7,373,195 | 9,751,645 | 60,460,199 | 302,300,995 |
| -1 | -5 | -31 | -41 | -155 | -205 | -1,271 | -6,355 | -47,569 | -237,845 | -1,474,639 | -1,950,329 | -7,373,195 | -9,751,645 | -60,460,199 | -302,300,995 |
