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 302,687,665, 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 | 302,687,665 | |
| -1 | -302,687,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,687,665.
Example:
1 x 302,687,665 = 302,687,665
and
-1 x -302,687,665 = 302,687,665
Notice both answers equal 302,687,665
With that explanation out of the way, let's continue. Next, we take the number 302,687,665 and divide it by 2:
302,687,665 ÷ 2 = 151,343,832.5
If the quotient is a whole number, then 2 and 151,343,832.5 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 | 302,687,665 | |
| -1 | -302,687,665 |
Now, we try dividing 302,687,665 by 3:
302,687,665 ÷ 3 = 100,895,888.3333
If the quotient is a whole number, then 3 and 100,895,888.3333 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 | 302,687,665 | |
| -1 | -302,687,665 |
Let's try dividing by 4:
302,687,665 ÷ 4 = 75,671,916.25
If the quotient is a whole number, then 4 and 75,671,916.25 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 | 302,687,665 | |
| -1 | 302,687,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 89 | 445 | 623 | 3,115 | 97,171 | 485,855 | 680,197 | 3,400,985 | 8,648,219 | 43,241,095 | 60,537,533 | 302,687,665 |
| -1 | -5 | -7 | -35 | -89 | -445 | -623 | -3,115 | -97,171 | -485,855 | -680,197 | -3,400,985 | -8,648,219 | -43,241,095 | -60,537,533 | -302,687,665 |
