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 718,268,863, 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 | 718,268,863 | |
| -1 | -718,268,863 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 718,268,863.
Example:
1 x 718,268,863 = 718,268,863
and
-1 x -718,268,863 = 718,268,863
Notice both answers equal 718,268,863
With that explanation out of the way, let's continue. Next, we take the number 718,268,863 and divide it by 2:
718,268,863 ÷ 2 = 359,134,431.5
If the quotient is a whole number, then 2 and 359,134,431.5 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 | 718,268,863 | |
| -1 | -718,268,863 |
Now, we try dividing 718,268,863 by 3:
718,268,863 ÷ 3 = 239,422,954.3333
If the quotient is a whole number, then 3 and 239,422,954.3333 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 | 718,268,863 | |
| -1 | -718,268,863 |
Let's try dividing by 4:
718,268,863 ÷ 4 = 179,567,215.75
If the quotient is a whole number, then 4 and 179,567,215.75 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 | 718,268,863 | |
| -1 | 718,268,863 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 299 | 1,493 | 1,609 | 19,409 | 20,917 | 34,339 | 37,007 | 446,407 | 481,091 | 2,402,237 | 31,229,081 | 55,251,451 | 718,268,863 |
| -1 | -13 | -23 | -299 | -1,493 | -1,609 | -19,409 | -20,917 | -34,339 | -37,007 | -446,407 | -481,091 | -2,402,237 | -31,229,081 | -55,251,451 | -718,268,863 |
