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 8,029,021, 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 | 8,029,021 | |
| -1 | -8,029,021 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,029,021.
Example:
1 x 8,029,021 = 8,029,021
and
-1 x -8,029,021 = 8,029,021
Notice both answers equal 8,029,021
With that explanation out of the way, let's continue. Next, we take the number 8,029,021 and divide it by 2:
8,029,021 ÷ 2 = 4,014,510.5
If the quotient is a whole number, then 2 and 4,014,510.5 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 | 8,029,021 | |
| -1 | -8,029,021 |
Now, we try dividing 8,029,021 by 3:
8,029,021 ÷ 3 = 2,676,340.3333
If the quotient is a whole number, then 3 and 2,676,340.3333 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 | 8,029,021 | |
| -1 | -8,029,021 |
Let's try dividing by 4:
8,029,021 ÷ 4 = 2,007,255.25
If the quotient is a whole number, then 4 and 2,007,255.25 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 | 8,029,021 | |
| -1 | 8,029,021 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 169 | 617 | 1,001 | 1,183 | 1,859 | 4,319 | 6,787 | 8,021 | 13,013 | 47,509 | 56,147 | 88,231 | 104,273 | 617,617 | 729,911 | 1,147,003 | 8,029,021 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -169 | -617 | -1,001 | -1,183 | -1,859 | -4,319 | -6,787 | -8,021 | -13,013 | -47,509 | -56,147 | -88,231 | -104,273 | -617,617 | -729,911 | -1,147,003 | -8,029,021 |
