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 3,885,505, 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 | 3,885,505 | |
| -1 | -3,885,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,885,505.
Example:
1 x 3,885,505 = 3,885,505
and
-1 x -3,885,505 = 3,885,505
Notice both answers equal 3,885,505
With that explanation out of the way, let's continue. Next, we take the number 3,885,505 and divide it by 2:
3,885,505 ÷ 2 = 1,942,752.5
If the quotient is a whole number, then 2 and 1,942,752.5 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 | 3,885,505 | |
| -1 | -3,885,505 |
Now, we try dividing 3,885,505 by 3:
3,885,505 ÷ 3 = 1,295,168.3333
If the quotient is a whole number, then 3 and 1,295,168.3333 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 | 3,885,505 | |
| -1 | -3,885,505 |
Let's try dividing by 4:
3,885,505 ÷ 4 = 971,376.25
If the quotient is a whole number, then 4 and 971,376.25 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 | 3,885,505 | |
| -1 | 3,885,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 23 | 65 | 113 | 115 | 299 | 529 | 565 | 1,469 | 1,495 | 2,599 | 2,645 | 6,877 | 7,345 | 12,995 | 33,787 | 34,385 | 59,777 | 168,935 | 298,885 | 777,101 | 3,885,505 |
| -1 | -5 | -13 | -23 | -65 | -113 | -115 | -299 | -529 | -565 | -1,469 | -1,495 | -2,599 | -2,645 | -6,877 | -7,345 | -12,995 | -33,787 | -34,385 | -59,777 | -168,935 | -298,885 | -777,101 | -3,885,505 |
