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 718,066,313, 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 | 718,066,313 | |
| -1 | -718,066,313 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 718,066,313.
Example:
1 x 718,066,313 = 718,066,313
and
-1 x -718,066,313 = 718,066,313
Notice both answers equal 718,066,313
With that explanation out of the way, let's continue. Next, we take the number 718,066,313 and divide it by 2:
718,066,313 ÷ 2 = 359,033,156.5
If the quotient is a whole number, then 2 and 359,033,156.5 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 | 718,066,313 | |
| -1 | -718,066,313 |
Now, we try dividing 718,066,313 by 3:
718,066,313 ÷ 3 = 239,355,437.6667
If the quotient is a whole number, then 3 and 239,355,437.6667 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 | 718,066,313 | |
| -1 | -718,066,313 |
Let's try dividing by 4:
718,066,313 ÷ 4 = 179,516,578.25
If the quotient is a whole number, then 4 and 179,516,578.25 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 | 718,066,313 | |
| -1 | 718,066,313 |
If you did it right, you will end up with this table:
| 1 | 53 | 79 | 149 | 1,151 | 4,187 | 7,897 | 11,771 | 61,003 | 90,929 | 171,499 | 623,863 | 4,819,237 | 9,089,447 | 13,548,421 | 718,066,313 |
| -1 | -53 | -79 | -149 | -1,151 | -4,187 | -7,897 | -11,771 | -61,003 | -90,929 | -171,499 | -623,863 | -4,819,237 | -9,089,447 | -13,548,421 | -718,066,313 |
