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 766,061,485, 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 | 766,061,485 | |
| -1 | -766,061,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 766,061,485.
Example:
1 x 766,061,485 = 766,061,485
and
-1 x -766,061,485 = 766,061,485
Notice both answers equal 766,061,485
With that explanation out of the way, let's continue. Next, we take the number 766,061,485 and divide it by 2:
766,061,485 ÷ 2 = 383,030,742.5
If the quotient is a whole number, then 2 and 383,030,742.5 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 | 766,061,485 | |
| -1 | -766,061,485 |
Now, we try dividing 766,061,485 by 3:
766,061,485 ÷ 3 = 255,353,828.3333
If the quotient is a whole number, then 3 and 255,353,828.3333 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 | 766,061,485 | |
| -1 | -766,061,485 |
Let's try dividing by 4:
766,061,485 ÷ 4 = 191,515,371.25
If the quotient is a whole number, then 4 and 191,515,371.25 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 | 766,061,485 | |
| -1 | 766,061,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 61 | 305 | 427 | 2,135 | 358,811 | 1,794,055 | 2,511,677 | 12,558,385 | 21,887,471 | 109,437,355 | 153,212,297 | 766,061,485 |
| -1 | -5 | -7 | -35 | -61 | -305 | -427 | -2,135 | -358,811 | -1,794,055 | -2,511,677 | -12,558,385 | -21,887,471 | -109,437,355 | -153,212,297 | -766,061,485 |
