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 28,211,029, 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 | 28,211,029 | |
| -1 | -28,211,029 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,211,029.
Example:
1 x 28,211,029 = 28,211,029
and
-1 x -28,211,029 = 28,211,029
Notice both answers equal 28,211,029
With that explanation out of the way, let's continue. Next, we take the number 28,211,029 and divide it by 2:
28,211,029 ÷ 2 = 14,105,514.5
If the quotient is a whole number, then 2 and 14,105,514.5 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 | 28,211,029 | |
| -1 | -28,211,029 |
Now, we try dividing 28,211,029 by 3:
28,211,029 ÷ 3 = 9,403,676.3333
If the quotient is a whole number, then 3 and 9,403,676.3333 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 | 28,211,029 | |
| -1 | -28,211,029 |
Let's try dividing by 4:
28,211,029 ÷ 4 = 7,052,757.25
If the quotient is a whole number, then 4 and 7,052,757.25 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 | 28,211,029 | |
| -1 | 28,211,029 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 19 | 77 | 121 | 133 | 209 | 847 | 1,463 | 1,753 | 2,299 | 12,271 | 16,093 | 19,283 | 33,307 | 134,981 | 212,113 | 233,149 | 366,377 | 1,484,791 | 2,564,639 | 4,030,147 | 28,211,029 |
| -1 | -7 | -11 | -19 | -77 | -121 | -133 | -209 | -847 | -1,463 | -1,753 | -2,299 | -12,271 | -16,093 | -19,283 | -33,307 | -134,981 | -212,113 | -233,149 | -366,377 | -1,484,791 | -2,564,639 | -4,030,147 | -28,211,029 |
