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 411,301,555, 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 | 411,301,555 | |
| -1 | -411,301,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 411,301,555.
Example:
1 x 411,301,555 = 411,301,555
and
-1 x -411,301,555 = 411,301,555
Notice both answers equal 411,301,555
With that explanation out of the way, let's continue. Next, we take the number 411,301,555 and divide it by 2:
411,301,555 ÷ 2 = 205,650,777.5
If the quotient is a whole number, then 2 and 205,650,777.5 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 | 411,301,555 | |
| -1 | -411,301,555 |
Now, we try dividing 411,301,555 by 3:
411,301,555 ÷ 3 = 137,100,518.3333
If the quotient is a whole number, then 3 and 137,100,518.3333 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 | 411,301,555 | |
| -1 | -411,301,555 |
Let's try dividing by 4:
411,301,555 ÷ 4 = 102,825,388.75
If the quotient is a whole number, then 4 and 102,825,388.75 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 | 411,301,555 | |
| -1 | 411,301,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,733 | 6,781 | 8,665 | 12,131 | 33,905 | 47,467 | 60,655 | 237,335 | 11,751,473 | 58,757,365 | 82,260,311 | 411,301,555 |
| -1 | -5 | -7 | -35 | -1,733 | -6,781 | -8,665 | -12,131 | -33,905 | -47,467 | -60,655 | -237,335 | -11,751,473 | -58,757,365 | -82,260,311 | -411,301,555 |
