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 763,646,411, 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 | 763,646,411 | |
| -1 | -763,646,411 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 763,646,411.
Example:
1 x 763,646,411 = 763,646,411
and
-1 x -763,646,411 = 763,646,411
Notice both answers equal 763,646,411
With that explanation out of the way, let's continue. Next, we take the number 763,646,411 and divide it by 2:
763,646,411 ÷ 2 = 381,823,205.5
If the quotient is a whole number, then 2 and 381,823,205.5 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 | 763,646,411 | |
| -1 | -763,646,411 |
Now, we try dividing 763,646,411 by 3:
763,646,411 ÷ 3 = 254,548,803.6667
If the quotient is a whole number, then 3 and 254,548,803.6667 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 | 763,646,411 | |
| -1 | -763,646,411 |
Let's try dividing by 4:
763,646,411 ÷ 4 = 190,911,602.75
If the quotient is a whole number, then 4 and 190,911,602.75 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 | 763,646,411 | |
| -1 | 763,646,411 |
If you did it right, you will end up with this table:
| 1 | 11 | 151 | 167 | 1,661 | 1,837 | 2,753 | 25,217 | 30,283 | 277,387 | 415,703 | 459,751 | 4,572,733 | 5,057,261 | 69,422,401 | 763,646,411 |
| -1 | -11 | -151 | -167 | -1,661 | -1,837 | -2,753 | -25,217 | -30,283 | -277,387 | -415,703 | -459,751 | -4,572,733 | -5,057,261 | -69,422,401 | -763,646,411 |
