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 18,192,827, 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 | 18,192,827 | |
| -1 | -18,192,827 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,192,827.
Example:
1 x 18,192,827 = 18,192,827
and
-1 x -18,192,827 = 18,192,827
Notice both answers equal 18,192,827
With that explanation out of the way, let's continue. Next, we take the number 18,192,827 and divide it by 2:
18,192,827 ÷ 2 = 9,096,413.5
If the quotient is a whole number, then 2 and 9,096,413.5 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 | 18,192,827 | |
| -1 | -18,192,827 |
Now, we try dividing 18,192,827 by 3:
18,192,827 ÷ 3 = 6,064,275.6667
If the quotient is a whole number, then 3 and 6,064,275.6667 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 | 18,192,827 | |
| -1 | -18,192,827 |
Let's try dividing by 4:
18,192,827 ÷ 4 = 4,548,206.75
If the quotient is a whole number, then 4 and 4,548,206.75 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 | 18,192,827 | |
| -1 | 18,192,827 |
If you did it right, you will end up with this table:
| 1 | 43 | 59 | 71 | 101 | 2,537 | 3,053 | 4,189 | 4,343 | 5,959 | 7,171 | 180,127 | 256,237 | 308,353 | 423,089 | 18,192,827 |
| -1 | -43 | -59 | -71 | -101 | -2,537 | -3,053 | -4,189 | -4,343 | -5,959 | -7,171 | -180,127 | -256,237 | -308,353 | -423,089 | -18,192,827 |
