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 18,824,351, 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 | 18,824,351 | |
| -1 | -18,824,351 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,824,351.
Example:
1 x 18,824,351 = 18,824,351
and
-1 x -18,824,351 = 18,824,351
Notice both answers equal 18,824,351
With that explanation out of the way, let's continue. Next, we take the number 18,824,351 and divide it by 2:
18,824,351 ÷ 2 = 9,412,175.5
If the quotient is a whole number, then 2 and 9,412,175.5 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 | 18,824,351 | |
| -1 | -18,824,351 |
Now, we try dividing 18,824,351 by 3:
18,824,351 ÷ 3 = 6,274,783.6667
If the quotient is a whole number, then 3 and 6,274,783.6667 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 | 18,824,351 | |
| -1 | -18,824,351 |
Let's try dividing by 4:
18,824,351 ÷ 4 = 4,706,087.75
If the quotient is a whole number, then 4 and 4,706,087.75 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 | 18,824,351 | |
| -1 | 18,824,351 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 269 | 769 | 1,883 | 3,497 | 5,383 | 9,997 | 24,479 | 69,979 | 206,861 | 1,448,027 | 2,689,193 | 18,824,351 |
| -1 | -7 | -13 | -91 | -269 | -769 | -1,883 | -3,497 | -5,383 | -9,997 | -24,479 | -69,979 | -206,861 | -1,448,027 | -2,689,193 | -18,824,351 |
