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 743,656,999, 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 | 743,656,999 | |
| -1 | -743,656,999 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 743,656,999.
Example:
1 x 743,656,999 = 743,656,999
and
-1 x -743,656,999 = 743,656,999
Notice both answers equal 743,656,999
With that explanation out of the way, let's continue. Next, we take the number 743,656,999 and divide it by 2:
743,656,999 ÷ 2 = 371,828,499.5
If the quotient is a whole number, then 2 and 371,828,499.5 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 | 743,656,999 | |
| -1 | -743,656,999 |
Now, we try dividing 743,656,999 by 3:
743,656,999 ÷ 3 = 247,885,666.3333
If the quotient is a whole number, then 3 and 247,885,666.3333 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 | 743,656,999 | |
| -1 | -743,656,999 |
Let's try dividing by 4:
743,656,999 ÷ 4 = 185,914,249.75
If the quotient is a whole number, then 4 and 185,914,249.75 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 | 743,656,999 | |
| -1 | 743,656,999 |
If you did it right, you will end up with this table:
| 1 | 23 | 97 | 257 | 1,297 | 2,231 | 5,911 | 24,929 | 29,831 | 125,809 | 333,329 | 573,367 | 2,893,607 | 7,666,567 | 32,332,913 | 743,656,999 |
| -1 | -23 | -97 | -257 | -1,297 | -2,231 | -5,911 | -24,929 | -29,831 | -125,809 | -333,329 | -573,367 | -2,893,607 | -7,666,567 | -32,332,913 | -743,656,999 |
