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 764,757,799, 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 | 764,757,799 | |
| -1 | -764,757,799 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 764,757,799.
Example:
1 x 764,757,799 = 764,757,799
and
-1 x -764,757,799 = 764,757,799
Notice both answers equal 764,757,799
With that explanation out of the way, let's continue. Next, we take the number 764,757,799 and divide it by 2:
764,757,799 ÷ 2 = 382,378,899.5
If the quotient is a whole number, then 2 and 382,378,899.5 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 | 764,757,799 | |
| -1 | -764,757,799 |
Now, we try dividing 764,757,799 by 3:
764,757,799 ÷ 3 = 254,919,266.3333
If the quotient is a whole number, then 3 and 254,919,266.3333 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 | 764,757,799 | |
| -1 | -764,757,799 |
Let's try dividing by 4:
764,757,799 ÷ 4 = 191,189,449.75
If the quotient is a whole number, then 4 and 191,189,449.75 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 | 764,757,799 | |
| -1 | 764,757,799 |
If you did it right, you will end up with this table:
| 1 | 13 | 103 | 467 | 1,223 | 1,339 | 6,071 | 15,899 | 48,101 | 125,969 | 571,141 | 625,313 | 1,637,597 | 7,424,833 | 58,827,523 | 764,757,799 |
| -1 | -13 | -103 | -467 | -1,223 | -1,339 | -6,071 | -15,899 | -48,101 | -125,969 | -571,141 | -625,313 | -1,637,597 | -7,424,833 | -58,827,523 | -764,757,799 |
