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 6,783,007, 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 | 6,783,007 | |
| -1 | -6,783,007 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,783,007.
Example:
1 x 6,783,007 = 6,783,007
and
-1 x -6,783,007 = 6,783,007
Notice both answers equal 6,783,007
With that explanation out of the way, let's continue. Next, we take the number 6,783,007 and divide it by 2:
6,783,007 ÷ 2 = 3,391,503.5
If the quotient is a whole number, then 2 and 3,391,503.5 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 | 6,783,007 | |
| -1 | -6,783,007 |
Now, we try dividing 6,783,007 by 3:
6,783,007 ÷ 3 = 2,261,002.3333
If the quotient is a whole number, then 3 and 2,261,002.3333 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 | 6,783,007 | |
| -1 | -6,783,007 |
Let's try dividing by 4:
6,783,007 ÷ 4 = 1,695,751.75
If the quotient is a whole number, then 4 and 1,695,751.75 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 | 6,783,007 | |
| -1 | 6,783,007 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 137 | 643 | 959 | 1,507 | 4,501 | 7,073 | 10,549 | 49,511 | 88,091 | 616,637 | 969,001 | 6,783,007 |
| -1 | -7 | -11 | -77 | -137 | -643 | -959 | -1,507 | -4,501 | -7,073 | -10,549 | -49,511 | -88,091 | -616,637 | -969,001 | -6,783,007 |
