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 18,455,455, 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 | 18,455,455 | |
| -1 | -18,455,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,455,455.
Example:
1 x 18,455,455 = 18,455,455
and
-1 x -18,455,455 = 18,455,455
Notice both answers equal 18,455,455
With that explanation out of the way, let's continue. Next, we take the number 18,455,455 and divide it by 2:
18,455,455 ÷ 2 = 9,227,727.5
If the quotient is a whole number, then 2 and 9,227,727.5 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 | 18,455,455 | |
| -1 | -18,455,455 |
Now, we try dividing 18,455,455 by 3:
18,455,455 ÷ 3 = 6,151,818.3333
If the quotient is a whole number, then 3 and 6,151,818.3333 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 | 18,455,455 | |
| -1 | -18,455,455 |
Let's try dividing by 4:
18,455,455 ÷ 4 = 4,613,863.75
If the quotient is a whole number, then 4 and 4,613,863.75 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 | 18,455,455 | |
| -1 | 18,455,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 29 | 85 | 145 | 493 | 2,465 | 7,487 | 37,435 | 127,279 | 217,123 | 636,395 | 1,085,615 | 3,691,091 | 18,455,455 |
| -1 | -5 | -17 | -29 | -85 | -145 | -493 | -2,465 | -7,487 | -37,435 | -127,279 | -217,123 | -636,395 | -1,085,615 | -3,691,091 | -18,455,455 |
