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 411,111,565, 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 | 411,111,565 | |
| -1 | -411,111,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 411,111,565.
Example:
1 x 411,111,565 = 411,111,565
and
-1 x -411,111,565 = 411,111,565
Notice both answers equal 411,111,565
With that explanation out of the way, let's continue. Next, we take the number 411,111,565 and divide it by 2:
411,111,565 ÷ 2 = 205,555,782.5
If the quotient is a whole number, then 2 and 205,555,782.5 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 | 411,111,565 | |
| -1 | -411,111,565 |
Now, we try dividing 411,111,565 by 3:
411,111,565 ÷ 3 = 137,037,188.3333
If the quotient is a whole number, then 3 and 137,037,188.3333 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 | 411,111,565 | |
| -1 | -411,111,565 |
Let's try dividing by 4:
411,111,565 ÷ 4 = 102,777,891.25
If the quotient is a whole number, then 4 and 102,777,891.25 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 | 411,111,565 | |
| -1 | 411,111,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 157 | 367 | 785 | 1,427 | 1,835 | 7,135 | 57,619 | 224,039 | 288,095 | 523,709 | 1,120,195 | 2,618,545 | 82,222,313 | 411,111,565 |
| -1 | -5 | -157 | -367 | -785 | -1,427 | -1,835 | -7,135 | -57,619 | -224,039 | -288,095 | -523,709 | -1,120,195 | -2,618,545 | -82,222,313 | -411,111,565 |
