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 302,470,079, 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 | 302,470,079 | |
| -1 | -302,470,079 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,470,079.
Example:
1 x 302,470,079 = 302,470,079
and
-1 x -302,470,079 = 302,470,079
Notice both answers equal 302,470,079
With that explanation out of the way, let's continue. Next, we take the number 302,470,079 and divide it by 2:
302,470,079 ÷ 2 = 151,235,039.5
If the quotient is a whole number, then 2 and 151,235,039.5 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 | 302,470,079 | |
| -1 | -302,470,079 |
Now, we try dividing 302,470,079 by 3:
302,470,079 ÷ 3 = 100,823,359.6667
If the quotient is a whole number, then 3 and 100,823,359.6667 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 | 302,470,079 | |
| -1 | -302,470,079 |
Let's try dividing by 4:
302,470,079 ÷ 4 = 75,617,519.75
If the quotient is a whole number, then 4 and 75,617,519.75 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 | 302,470,079 | |
| -1 | 302,470,079 |
If you did it right, you will end up with this table:
| 1 | 23 | 37 | 41 | 851 | 943 | 1,517 | 8,669 | 34,891 | 199,387 | 320,753 | 355,429 | 7,377,319 | 8,174,867 | 13,150,873 | 302,470,079 |
| -1 | -23 | -37 | -41 | -851 | -943 | -1,517 | -8,669 | -34,891 | -199,387 | -320,753 | -355,429 | -7,377,319 | -8,174,867 | -13,150,873 | -302,470,079 |
