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 768,614,063, 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 | 768,614,063 | |
| -1 | -768,614,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 768,614,063.
Example:
1 x 768,614,063 = 768,614,063
and
-1 x -768,614,063 = 768,614,063
Notice both answers equal 768,614,063
With that explanation out of the way, let's continue. Next, we take the number 768,614,063 and divide it by 2:
768,614,063 ÷ 2 = 384,307,031.5
If the quotient is a whole number, then 2 and 384,307,031.5 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 | 768,614,063 | |
| -1 | -768,614,063 |
Now, we try dividing 768,614,063 by 3:
768,614,063 ÷ 3 = 256,204,687.6667
If the quotient is a whole number, then 3 and 256,204,687.6667 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 | 768,614,063 | |
| -1 | -768,614,063 |
Let's try dividing by 4:
768,614,063 ÷ 4 = 192,153,515.75
If the quotient is a whole number, then 4 and 192,153,515.75 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 | 768,614,063 | |
| -1 | 768,614,063 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 107 | 413 | 749 | 6,313 | 17,393 | 44,191 | 121,751 | 1,026,187 | 1,861,051 | 7,183,309 | 13,027,357 | 109,802,009 | 768,614,063 |
| -1 | -7 | -59 | -107 | -413 | -749 | -6,313 | -17,393 | -44,191 | -121,751 | -1,026,187 | -1,861,051 | -7,183,309 | -13,027,357 | -109,802,009 | -768,614,063 |
