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 6,633,781, 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 | 6,633,781 | |
| -1 | -6,633,781 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,633,781.
Example:
1 x 6,633,781 = 6,633,781
and
-1 x -6,633,781 = 6,633,781
Notice both answers equal 6,633,781
With that explanation out of the way, let's continue. Next, we take the number 6,633,781 and divide it by 2:
6,633,781 ÷ 2 = 3,316,890.5
If the quotient is a whole number, then 2 and 3,316,890.5 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 | 6,633,781 | |
| -1 | -6,633,781 |
Now, we try dividing 6,633,781 by 3:
6,633,781 ÷ 3 = 2,211,260.3333
If the quotient is a whole number, then 3 and 2,211,260.3333 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 | 6,633,781 | |
| -1 | -6,633,781 |
Let's try dividing by 4:
6,633,781 ÷ 4 = 1,658,445.25
If the quotient is a whole number, then 4 and 1,658,445.25 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 | 6,633,781 | |
| -1 | 6,633,781 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 101 | 707 | 853 | 1,111 | 5,971 | 7,777 | 9,383 | 65,681 | 86,153 | 603,071 | 947,683 | 6,633,781 |
| -1 | -7 | -11 | -77 | -101 | -707 | -853 | -1,111 | -5,971 | -7,777 | -9,383 | -65,681 | -86,153 | -603,071 | -947,683 | -6,633,781 |
