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 302,032,319, 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 | 302,032,319 | |
| -1 | -302,032,319 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,032,319.
Example:
1 x 302,032,319 = 302,032,319
and
-1 x -302,032,319 = 302,032,319
Notice both answers equal 302,032,319
With that explanation out of the way, let's continue. Next, we take the number 302,032,319 and divide it by 2:
302,032,319 ÷ 2 = 151,016,159.5
If the quotient is a whole number, then 2 and 151,016,159.5 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 | 302,032,319 | |
| -1 | -302,032,319 |
Now, we try dividing 302,032,319 by 3:
302,032,319 ÷ 3 = 100,677,439.6667
If the quotient is a whole number, then 3 and 100,677,439.6667 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 | 302,032,319 | |
| -1 | -302,032,319 |
Let's try dividing by 4:
302,032,319 ÷ 4 = 75,508,079.75
If the quotient is a whole number, then 4 and 75,508,079.75 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 | 302,032,319 | |
| -1 | 302,032,319 |
If you did it right, you will end up with this table:
| 1 | 17 | 53 | 101 | 901 | 1,717 | 3,319 | 5,353 | 56,423 | 91,001 | 175,907 | 335,219 | 2,990,419 | 5,698,723 | 17,766,607 | 302,032,319 |
| -1 | -17 | -53 | -101 | -901 | -1,717 | -3,319 | -5,353 | -56,423 | -91,001 | -175,907 | -335,219 | -2,990,419 | -5,698,723 | -17,766,607 | -302,032,319 |
