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 731,433,787, 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 | 731,433,787 | |
| -1 | -731,433,787 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 731,433,787.
Example:
1 x 731,433,787 = 731,433,787
and
-1 x -731,433,787 = 731,433,787
Notice both answers equal 731,433,787
With that explanation out of the way, let's continue. Next, we take the number 731,433,787 and divide it by 2:
731,433,787 ÷ 2 = 365,716,893.5
If the quotient is a whole number, then 2 and 365,716,893.5 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 | 731,433,787 | |
| -1 | -731,433,787 |
Now, we try dividing 731,433,787 by 3:
731,433,787 ÷ 3 = 243,811,262.3333
If the quotient is a whole number, then 3 and 243,811,262.3333 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 | 731,433,787 | |
| -1 | -731,433,787 |
Let's try dividing by 4:
731,433,787 ÷ 4 = 182,858,446.75
If the quotient is a whole number, then 4 and 182,858,446.75 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 | 731,433,787 | |
| -1 | 731,433,787 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 47 | 161 | 329 | 1,081 | 7,567 | 96,661 | 676,627 | 2,223,203 | 4,543,067 | 15,562,421 | 31,801,469 | 104,490,541 | 731,433,787 |
| -1 | -7 | -23 | -47 | -161 | -329 | -1,081 | -7,567 | -96,661 | -676,627 | -2,223,203 | -4,543,067 | -15,562,421 | -31,801,469 | -104,490,541 | -731,433,787 |
