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 747,383,867, 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 | 747,383,867 | |
| -1 | -747,383,867 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 747,383,867.
Example:
1 x 747,383,867 = 747,383,867
and
-1 x -747,383,867 = 747,383,867
Notice both answers equal 747,383,867
With that explanation out of the way, let's continue. Next, we take the number 747,383,867 and divide it by 2:
747,383,867 ÷ 2 = 373,691,933.5
If the quotient is a whole number, then 2 and 373,691,933.5 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 | 747,383,867 | |
| -1 | -747,383,867 |
Now, we try dividing 747,383,867 by 3:
747,383,867 ÷ 3 = 249,127,955.6667
If the quotient is a whole number, then 3 and 249,127,955.6667 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 | 747,383,867 | |
| -1 | -747,383,867 |
Let's try dividing by 4:
747,383,867 ÷ 4 = 186,845,966.75
If the quotient is a whole number, then 4 and 186,845,966.75 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 | 747,383,867 | |
| -1 | 747,383,867 |
If you did it right, you will end up with this table:
| 1 | 19 | 31 | 589 | 1,069 | 1,187 | 20,311 | 22,553 | 33,139 | 36,797 | 629,641 | 699,143 | 1,268,903 | 24,109,157 | 39,335,993 | 747,383,867 |
| -1 | -19 | -31 | -589 | -1,069 | -1,187 | -20,311 | -22,553 | -33,139 | -36,797 | -629,641 | -699,143 | -1,268,903 | -24,109,157 | -39,335,993 | -747,383,867 |
