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 1,021,163, 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 | 1,021,163 | |
| -1 | -1,021,163 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,021,163.
Example:
1 x 1,021,163 = 1,021,163
and
-1 x -1,021,163 = 1,021,163
Notice both answers equal 1,021,163
With that explanation out of the way, let's continue. Next, we take the number 1,021,163 and divide it by 2:
1,021,163 ÷ 2 = 510,581.5
If the quotient is a whole number, then 2 and 510,581.5 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 | 1,021,163 | |
| -1 | -1,021,163 |
Now, we try dividing 1,021,163 by 3:
1,021,163 ÷ 3 = 340,387.6667
If the quotient is a whole number, then 3 and 340,387.6667 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 | 1,021,163 | |
| -1 | -1,021,163 |
Let's try dividing by 4:
1,021,163 ÷ 4 = 255,290.75
If the quotient is a whole number, then 4 and 255,290.75 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 | 1,021,163 | |
| -1 | 1,021,163 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 37 | 143 | 193 | 407 | 481 | 2,123 | 2,509 | 5,291 | 7,141 | 27,599 | 78,551 | 92,833 | 1,021,163 |
| -1 | -11 | -13 | -37 | -143 | -193 | -407 | -481 | -2,123 | -2,509 | -5,291 | -7,141 | -27,599 | -78,551 | -92,833 | -1,021,163 |
