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 306,352,045, 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 | 306,352,045 | |
| -1 | -306,352,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 306,352,045.
Example:
1 x 306,352,045 = 306,352,045
and
-1 x -306,352,045 = 306,352,045
Notice both answers equal 306,352,045
With that explanation out of the way, let's continue. Next, we take the number 306,352,045 and divide it by 2:
306,352,045 ÷ 2 = 153,176,022.5
If the quotient is a whole number, then 2 and 153,176,022.5 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 | 306,352,045 | |
| -1 | -306,352,045 |
Now, we try dividing 306,352,045 by 3:
306,352,045 ÷ 3 = 102,117,348.3333
If the quotient is a whole number, then 3 and 102,117,348.3333 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 | 306,352,045 | |
| -1 | -306,352,045 |
Let's try dividing by 4:
306,352,045 ÷ 4 = 76,588,011.25
If the quotient is a whole number, then 4 and 76,588,011.25 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 | 306,352,045 | |
| -1 | 306,352,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 821 | 2,017 | 4,105 | 10,085 | 30,377 | 74,629 | 151,885 | 373,145 | 1,655,957 | 8,279,785 | 61,270,409 | 306,352,045 |
| -1 | -5 | -37 | -185 | -821 | -2,017 | -4,105 | -10,085 | -30,377 | -74,629 | -151,885 | -373,145 | -1,655,957 | -8,279,785 | -61,270,409 | -306,352,045 |
