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 788,572,327, 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 | 788,572,327 | |
-1 | -788,572,327 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 788,572,327.
Example:
1 x 788,572,327 = 788,572,327
and
-1 x -788,572,327 = 788,572,327
Notice both answers equal 788,572,327
With that explanation out of the way, let's continue. Next, we take the number 788,572,327 and divide it by 2:
788,572,327 ÷ 2 = 394,286,163.5
If the quotient is a whole number, then 2 and 394,286,163.5 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 | 788,572,327 | |
-1 | -788,572,327 |
Now, we try dividing 788,572,327 by 3:
788,572,327 ÷ 3 = 262,857,442.3333
If the quotient is a whole number, then 3 and 262,857,442.3333 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 | 788,572,327 | |
-1 | -788,572,327 |
Let's try dividing by 4:
788,572,327 ÷ 4 = 197,143,081.75
If the quotient is a whole number, then 4 and 197,143,081.75 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 | 788,572,327 | |
-1 | 788,572,327 |
If you did it right, you will end up with this table:
1 | 31 | 25,437,817 | 788,572,327 |
-1 | -31 | -25,437,817 | -788,572,327 |
