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 65,252,681, 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 | 65,252,681 | |
| -1 | -65,252,681 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,252,681.
Example:
1 x 65,252,681 = 65,252,681
and
-1 x -65,252,681 = 65,252,681
Notice both answers equal 65,252,681
With that explanation out of the way, let's continue. Next, we take the number 65,252,681 and divide it by 2:
65,252,681 ÷ 2 = 32,626,340.5
If the quotient is a whole number, then 2 and 32,626,340.5 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 | 65,252,681 | |
| -1 | -65,252,681 |
Now, we try dividing 65,252,681 by 3:
65,252,681 ÷ 3 = 21,750,893.6667
If the quotient is a whole number, then 3 and 21,750,893.6667 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 | 65,252,681 | |
| -1 | -65,252,681 |
Let's try dividing by 4:
65,252,681 ÷ 4 = 16,313,170.25
If the quotient is a whole number, then 4 and 16,313,170.25 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 | 65,252,681 | |
| -1 | 65,252,681 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 503 | 587 | 6,539 | 7,631 | 8,551 | 9,979 | 111,163 | 129,727 | 295,261 | 3,838,393 | 5,019,437 | 65,252,681 |
| -1 | -13 | -17 | -221 | -503 | -587 | -6,539 | -7,631 | -8,551 | -9,979 | -111,163 | -129,727 | -295,261 | -3,838,393 | -5,019,437 | -65,252,681 |
