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 302,026,717, 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 | 302,026,717 | |
| -1 | -302,026,717 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,026,717.
Example:
1 x 302,026,717 = 302,026,717
and
-1 x -302,026,717 = 302,026,717
Notice both answers equal 302,026,717
With that explanation out of the way, let's continue. Next, we take the number 302,026,717 and divide it by 2:
302,026,717 ÷ 2 = 151,013,358.5
If the quotient is a whole number, then 2 and 151,013,358.5 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 | 302,026,717 | |
| -1 | -302,026,717 |
Now, we try dividing 302,026,717 by 3:
302,026,717 ÷ 3 = 100,675,572.3333
If the quotient is a whole number, then 3 and 100,675,572.3333 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 | 302,026,717 | |
| -1 | -302,026,717 |
Let's try dividing by 4:
302,026,717 ÷ 4 = 75,506,679.25
If the quotient is a whole number, then 4 and 75,506,679.25 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 | 302,026,717 | |
| -1 | 302,026,717 |
If you did it right, you will end up with this table:
| 1 | 19 | 79 | 311 | 647 | 1,501 | 5,909 | 12,293 | 24,569 | 51,113 | 201,217 | 466,811 | 971,147 | 3,823,123 | 15,896,143 | 302,026,717 |
| -1 | -19 | -79 | -311 | -647 | -1,501 | -5,909 | -12,293 | -24,569 | -51,113 | -201,217 | -466,811 | -971,147 | -3,823,123 | -15,896,143 | -302,026,717 |
