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 306,332,719, 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 | 306,332,719 | |
| -1 | -306,332,719 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 306,332,719.
Example:
1 x 306,332,719 = 306,332,719
and
-1 x -306,332,719 = 306,332,719
Notice both answers equal 306,332,719
With that explanation out of the way, let's continue. Next, we take the number 306,332,719 and divide it by 2:
306,332,719 ÷ 2 = 153,166,359.5
If the quotient is a whole number, then 2 and 153,166,359.5 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 | 306,332,719 | |
| -1 | -306,332,719 |
Now, we try dividing 306,332,719 by 3:
306,332,719 ÷ 3 = 102,110,906.3333
If the quotient is a whole number, then 3 and 102,110,906.3333 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 | 306,332,719 | |
| -1 | -306,332,719 |
Let's try dividing by 4:
306,332,719 ÷ 4 = 76,583,179.75
If the quotient is a whole number, then 4 and 76,583,179.75 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 | 306,332,719 | |
| -1 | 306,332,719 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 947 | 4,201 | 6,629 | 10,417 | 29,407 | 46,211 | 72,919 | 323,477 | 3,978,347 | 27,848,429 | 43,761,817 | 306,332,719 |
| -1 | -7 | -11 | -77 | -947 | -4,201 | -6,629 | -10,417 | -29,407 | -46,211 | -72,919 | -323,477 | -3,978,347 | -27,848,429 | -43,761,817 | -306,332,719 |
