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 28,242,797, 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 | 28,242,797 | |
| -1 | -28,242,797 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,242,797.
Example:
1 x 28,242,797 = 28,242,797
and
-1 x -28,242,797 = 28,242,797
Notice both answers equal 28,242,797
With that explanation out of the way, let's continue. Next, we take the number 28,242,797 and divide it by 2:
28,242,797 ÷ 2 = 14,121,398.5
If the quotient is a whole number, then 2 and 14,121,398.5 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 | 28,242,797 | |
| -1 | -28,242,797 |
Now, we try dividing 28,242,797 by 3:
28,242,797 ÷ 3 = 9,414,265.6667
If the quotient is a whole number, then 3 and 9,414,265.6667 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 | 28,242,797 | |
| -1 | -28,242,797 |
Let's try dividing by 4:
28,242,797 ÷ 4 = 7,060,699.25
If the quotient is a whole number, then 4 and 7,060,699.25 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 | 28,242,797 | |
| -1 | 28,242,797 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 19 | 187 | 209 | 323 | 3,553 | 7,949 | 87,439 | 135,133 | 151,031 | 1,486,463 | 1,661,341 | 2,567,527 | 28,242,797 |
| -1 | -11 | -17 | -19 | -187 | -209 | -323 | -3,553 | -7,949 | -87,439 | -135,133 | -151,031 | -1,486,463 | -1,661,341 | -2,567,527 | -28,242,797 |
