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 65,448,487, 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 | 65,448,487 | |
| -1 | -65,448,487 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,448,487.
Example:
1 x 65,448,487 = 65,448,487
and
-1 x -65,448,487 = 65,448,487
Notice both answers equal 65,448,487
With that explanation out of the way, let's continue. Next, we take the number 65,448,487 and divide it by 2:
65,448,487 ÷ 2 = 32,724,243.5
If the quotient is a whole number, then 2 and 32,724,243.5 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 | 65,448,487 | |
| -1 | -65,448,487 |
Now, we try dividing 65,448,487 by 3:
65,448,487 ÷ 3 = 21,816,162.3333
If the quotient is a whole number, then 3 and 21,816,162.3333 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 | 65,448,487 | |
| -1 | -65,448,487 |
Let's try dividing by 4:
65,448,487 ÷ 4 = 16,362,121.75
If the quotient is a whole number, then 4 and 16,362,121.75 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 | 65,448,487 | |
| -1 | 65,448,487 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 47 | 221 | 611 | 799 | 6,301 | 10,387 | 81,913 | 107,117 | 296,147 | 1,392,521 | 3,849,911 | 5,034,499 | 65,448,487 |
| -1 | -13 | -17 | -47 | -221 | -611 | -799 | -6,301 | -10,387 | -81,913 | -107,117 | -296,147 | -1,392,521 | -3,849,911 | -5,034,499 | -65,448,487 |
