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 705,116,765, 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 | 705,116,765 | |
| -1 | -705,116,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 705,116,765.
Example:
1 x 705,116,765 = 705,116,765
and
-1 x -705,116,765 = 705,116,765
Notice both answers equal 705,116,765
With that explanation out of the way, let's continue. Next, we take the number 705,116,765 and divide it by 2:
705,116,765 ÷ 2 = 352,558,382.5
If the quotient is a whole number, then 2 and 352,558,382.5 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 | 705,116,765 | |
| -1 | -705,116,765 |
Now, we try dividing 705,116,765 by 3:
705,116,765 ÷ 3 = 235,038,921.6667
If the quotient is a whole number, then 3 and 235,038,921.6667 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 | 705,116,765 | |
| -1 | -705,116,765 |
Let's try dividing by 4:
705,116,765 ÷ 4 = 176,279,191.25
If the quotient is a whole number, then 4 and 176,279,191.25 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 | 705,116,765 | |
| -1 | 705,116,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 97 | 257 | 485 | 1,285 | 5,657 | 24,929 | 28,285 | 124,645 | 548,729 | 1,453,849 | 2,743,645 | 7,269,245 | 141,023,353 | 705,116,765 |
| -1 | -5 | -97 | -257 | -485 | -1,285 | -5,657 | -24,929 | -28,285 | -124,645 | -548,729 | -1,453,849 | -2,743,645 | -7,269,245 | -141,023,353 | -705,116,765 |
