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 302,132,207, 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 | 302,132,207 | |
| -1 | -302,132,207 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,132,207.
Example:
1 x 302,132,207 = 302,132,207
and
-1 x -302,132,207 = 302,132,207
Notice both answers equal 302,132,207
With that explanation out of the way, let's continue. Next, we take the number 302,132,207 and divide it by 2:
302,132,207 ÷ 2 = 151,066,103.5
If the quotient is a whole number, then 2 and 151,066,103.5 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 | 302,132,207 | |
| -1 | -302,132,207 |
Now, we try dividing 302,132,207 by 3:
302,132,207 ÷ 3 = 100,710,735.6667
If the quotient is a whole number, then 3 and 100,710,735.6667 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 | 302,132,207 | |
| -1 | -302,132,207 |
Let's try dividing by 4:
302,132,207 ÷ 4 = 75,533,051.75
If the quotient is a whole number, then 4 and 75,533,051.75 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 | 302,132,207 | |
| -1 | 302,132,207 |
If you did it right, you will end up with this table:
| 1 | 13 | 61 | 139 | 793 | 1,807 | 2,741 | 8,479 | 35,633 | 110,227 | 167,201 | 380,999 | 2,173,613 | 4,952,987 | 23,240,939 | 302,132,207 |
| -1 | -13 | -61 | -139 | -793 | -1,807 | -2,741 | -8,479 | -35,633 | -110,227 | -167,201 | -380,999 | -2,173,613 | -4,952,987 | -23,240,939 | -302,132,207 |
