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 65,388,323, 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 | 65,388,323 | |
| -1 | -65,388,323 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,388,323.
Example:
1 x 65,388,323 = 65,388,323
and
-1 x -65,388,323 = 65,388,323
Notice both answers equal 65,388,323
With that explanation out of the way, let's continue. Next, we take the number 65,388,323 and divide it by 2:
65,388,323 ÷ 2 = 32,694,161.5
If the quotient is a whole number, then 2 and 32,694,161.5 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 | 65,388,323 | |
| -1 | -65,388,323 |
Now, we try dividing 65,388,323 by 3:
65,388,323 ÷ 3 = 21,796,107.6667
If the quotient is a whole number, then 3 and 21,796,107.6667 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 | 65,388,323 | |
| -1 | -65,388,323 |
Let's try dividing by 4:
65,388,323 ÷ 4 = 16,347,080.75
If the quotient is a whole number, then 4 and 16,347,080.75 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 | 65,388,323 | |
| -1 | 65,388,323 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 65,323 | 457,261 | 718,553 | 849,199 | 5,029,871 | 5,944,393 | 9,341,189 | 65,388,323 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -65,323 | -457,261 | -718,553 | -849,199 | -5,029,871 | -5,944,393 | -9,341,189 | -65,388,323 |
