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 8,022,007, 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 | 8,022,007 | |
| -1 | -8,022,007 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,022,007.
Example:
1 x 8,022,007 = 8,022,007
and
-1 x -8,022,007 = 8,022,007
Notice both answers equal 8,022,007
With that explanation out of the way, let's continue. Next, we take the number 8,022,007 and divide it by 2:
8,022,007 ÷ 2 = 4,011,003.5
If the quotient is a whole number, then 2 and 4,011,003.5 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 | 8,022,007 | |
| -1 | -8,022,007 |
Now, we try dividing 8,022,007 by 3:
8,022,007 ÷ 3 = 2,674,002.3333
If the quotient is a whole number, then 3 and 2,674,002.3333 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 | 8,022,007 | |
| -1 | -8,022,007 |
Let's try dividing by 4:
8,022,007 ÷ 4 = 2,005,501.75
If the quotient is a whole number, then 4 and 2,005,501.75 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 | 8,022,007 | |
| -1 | 8,022,007 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 47 | 259 | 329 | 659 | 1,739 | 4,613 | 12,173 | 24,383 | 30,973 | 170,681 | 216,811 | 1,146,001 | 8,022,007 |
| -1 | -7 | -37 | -47 | -259 | -329 | -659 | -1,739 | -4,613 | -12,173 | -24,383 | -30,973 | -170,681 | -216,811 | -1,146,001 | -8,022,007 |
