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 765,582,107, 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 | 765,582,107 | |
| -1 | -765,582,107 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 765,582,107.
Example:
1 x 765,582,107 = 765,582,107
and
-1 x -765,582,107 = 765,582,107
Notice both answers equal 765,582,107
With that explanation out of the way, let's continue. Next, we take the number 765,582,107 and divide it by 2:
765,582,107 ÷ 2 = 382,791,053.5
If the quotient is a whole number, then 2 and 382,791,053.5 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 | 765,582,107 | |
| -1 | -765,582,107 |
Now, we try dividing 765,582,107 by 3:
765,582,107 ÷ 3 = 255,194,035.6667
If the quotient is a whole number, then 3 and 255,194,035.6667 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 | 765,582,107 | |
| -1 | -765,582,107 |
Let's try dividing by 4:
765,582,107 ÷ 4 = 191,395,526.75
If the quotient is a whole number, then 4 and 191,395,526.75 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 | 765,582,107 | |
| -1 | 765,582,107 |
If you did it right, you will end up with this table:
| 1 | 29 | 31 | 47 | 899 | 1,363 | 1,457 | 18,119 | 42,253 | 525,451 | 561,689 | 851,593 | 16,288,981 | 24,696,197 | 26,399,383 | 765,582,107 |
| -1 | -29 | -31 | -47 | -899 | -1,363 | -1,457 | -18,119 | -42,253 | -525,451 | -561,689 | -851,593 | -16,288,981 | -24,696,197 | -26,399,383 | -765,582,107 |
