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 760,217,135, 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 | 760,217,135 | |
| -1 | -760,217,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 760,217,135.
Example:
1 x 760,217,135 = 760,217,135
and
-1 x -760,217,135 = 760,217,135
Notice both answers equal 760,217,135
With that explanation out of the way, let's continue. Next, we take the number 760,217,135 and divide it by 2:
760,217,135 ÷ 2 = 380,108,567.5
If the quotient is a whole number, then 2 and 380,108,567.5 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 | 760,217,135 | |
| -1 | -760,217,135 |
Now, we try dividing 760,217,135 by 3:
760,217,135 ÷ 3 = 253,405,711.6667
If the quotient is a whole number, then 3 and 253,405,711.6667 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 | 760,217,135 | |
| -1 | -760,217,135 |
Let's try dividing by 4:
760,217,135 ÷ 4 = 190,054,283.75
If the quotient is a whole number, then 4 and 190,054,283.75 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 | 760,217,135 | |
| -1 | 760,217,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 2,543 | 3,517 | 12,715 | 17,585 | 43,231 | 59,789 | 216,155 | 298,945 | 8,943,731 | 44,718,655 | 152,043,427 | 760,217,135 |
| -1 | -5 | -17 | -85 | -2,543 | -3,517 | -12,715 | -17,585 | -43,231 | -59,789 | -216,155 | -298,945 | -8,943,731 | -44,718,655 | -152,043,427 | -760,217,135 |
