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 18,284,707, 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 | 18,284,707 | |
| -1 | -18,284,707 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,284,707.
Example:
1 x 18,284,707 = 18,284,707
and
-1 x -18,284,707 = 18,284,707
Notice both answers equal 18,284,707
With that explanation out of the way, let's continue. Next, we take the number 18,284,707 and divide it by 2:
18,284,707 ÷ 2 = 9,142,353.5
If the quotient is a whole number, then 2 and 9,142,353.5 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 | 18,284,707 | |
| -1 | -18,284,707 |
Now, we try dividing 18,284,707 by 3:
18,284,707 ÷ 3 = 6,094,902.3333
If the quotient is a whole number, then 3 and 6,094,902.3333 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 | 18,284,707 | |
| -1 | -18,284,707 |
Let's try dividing by 4:
18,284,707 ÷ 4 = 4,571,176.75
If the quotient is a whole number, then 4 and 4,571,176.75 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 | 18,284,707 | |
| -1 | 18,284,707 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 19 | 119 | 133 | 323 | 2,261 | 8,087 | 56,609 | 137,479 | 153,653 | 962,353 | 1,075,571 | 2,612,101 | 18,284,707 |
| -1 | -7 | -17 | -19 | -119 | -133 | -323 | -2,261 | -8,087 | -56,609 | -137,479 | -153,653 | -962,353 | -1,075,571 | -2,612,101 | -18,284,707 |
