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 1,006,621, 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 | 1,006,621 | |
| -1 | -1,006,621 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,006,621.
Example:
1 x 1,006,621 = 1,006,621
and
-1 x -1,006,621 = 1,006,621
Notice both answers equal 1,006,621
With that explanation out of the way, let's continue. Next, we take the number 1,006,621 and divide it by 2:
1,006,621 ÷ 2 = 503,310.5
If the quotient is a whole number, then 2 and 503,310.5 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 | 1,006,621 | |
| -1 | -1,006,621 |
Now, we try dividing 1,006,621 by 3:
1,006,621 ÷ 3 = 335,540.3333
If the quotient is a whole number, then 3 and 335,540.3333 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 | 1,006,621 | |
| -1 | -1,006,621 |
Let's try dividing by 4:
1,006,621 ÷ 4 = 251,655.25
If the quotient is a whole number, then 4 and 251,655.25 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 | 1,006,621 | |
| -1 | 1,006,621 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 187 | 769 | 1,309 | 5,383 | 8,459 | 13,073 | 59,213 | 91,511 | 143,803 | 1,006,621 |
| -1 | -7 | -11 | -17 | -77 | -119 | -187 | -769 | -1,309 | -5,383 | -8,459 | -13,073 | -59,213 | -91,511 | -143,803 | -1,006,621 |
