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 760,322,105, 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 | 760,322,105 | |
| -1 | -760,322,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 760,322,105.
Example:
1 x 760,322,105 = 760,322,105
and
-1 x -760,322,105 = 760,322,105
Notice both answers equal 760,322,105
With that explanation out of the way, let's continue. Next, we take the number 760,322,105 and divide it by 2:
760,322,105 ÷ 2 = 380,161,052.5
If the quotient is a whole number, then 2 and 380,161,052.5 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 | 760,322,105 | |
| -1 | -760,322,105 |
Now, we try dividing 760,322,105 by 3:
760,322,105 ÷ 3 = 253,440,701.6667
If the quotient is a whole number, then 3 and 253,440,701.6667 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 | 760,322,105 | |
| -1 | -760,322,105 |
Let's try dividing by 4:
760,322,105 ÷ 4 = 190,080,526.25
If the quotient is a whole number, then 4 and 190,080,526.25 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 | 760,322,105 | |
| -1 | 760,322,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 233 | 445 | 1,165 | 7,333 | 20,737 | 36,665 | 103,685 | 652,637 | 1,708,589 | 3,263,185 | 8,542,945 | 152,064,421 | 760,322,105 |
| -1 | -5 | -89 | -233 | -445 | -1,165 | -7,333 | -20,737 | -36,665 | -103,685 | -652,637 | -1,708,589 | -3,263,185 | -8,542,945 | -152,064,421 | -760,322,105 |
