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 788,432,567, 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 | 788,432,567 | |
| -1 | -788,432,567 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 788,432,567.
Example:
1 x 788,432,567 = 788,432,567
and
-1 x -788,432,567 = 788,432,567
Notice both answers equal 788,432,567
With that explanation out of the way, let's continue. Next, we take the number 788,432,567 and divide it by 2:
788,432,567 ÷ 2 = 394,216,283.5
If the quotient is a whole number, then 2 and 394,216,283.5 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 | 788,432,567 | |
| -1 | -788,432,567 |
Now, we try dividing 788,432,567 by 3:
788,432,567 ÷ 3 = 262,810,855.6667
If the quotient is a whole number, then 3 and 262,810,855.6667 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 | 788,432,567 | |
| -1 | -788,432,567 |
Let's try dividing by 4:
788,432,567 ÷ 4 = 197,108,141.75
If the quotient is a whole number, then 4 and 197,108,141.75 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 | 788,432,567 | |
| -1 | 788,432,567 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 257 | 611 | 3,341 | 5,021 | 12,079 | 65,273 | 157,027 | 235,987 | 1,290,397 | 3,067,831 | 16,775,161 | 60,648,659 | 788,432,567 |
| -1 | -13 | -47 | -257 | -611 | -3,341 | -5,021 | -12,079 | -65,273 | -157,027 | -235,987 | -1,290,397 | -3,067,831 | -16,775,161 | -60,648,659 | -788,432,567 |
