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 18,435,175, 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 | 18,435,175 | |
| -1 | -18,435,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,435,175.
Example:
1 x 18,435,175 = 18,435,175
and
-1 x -18,435,175 = 18,435,175
Notice both answers equal 18,435,175
With that explanation out of the way, let's continue. Next, we take the number 18,435,175 and divide it by 2:
18,435,175 ÷ 2 = 9,217,587.5
If the quotient is a whole number, then 2 and 9,217,587.5 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 | 18,435,175 | |
| -1 | -18,435,175 |
Now, we try dividing 18,435,175 by 3:
18,435,175 ÷ 3 = 6,145,058.3333
If the quotient is a whole number, then 3 and 6,145,058.3333 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 | 18,435,175 | |
| -1 | -18,435,175 |
Let's try dividing by 4:
18,435,175 ÷ 4 = 4,608,793.75
If the quotient is a whole number, then 4 and 4,608,793.75 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 | 18,435,175 | |
| -1 | 18,435,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 43 | 55 | 215 | 275 | 473 | 1,075 | 1,559 | 2,365 | 7,795 | 11,825 | 17,149 | 38,975 | 67,037 | 85,745 | 335,185 | 428,725 | 737,407 | 1,675,925 | 3,687,035 | 18,435,175 |
| -1 | -5 | -11 | -25 | -43 | -55 | -215 | -275 | -473 | -1,075 | -1,559 | -2,365 | -7,795 | -11,825 | -17,149 | -38,975 | -67,037 | -85,745 | -335,185 | -428,725 | -737,407 | -1,675,925 | -3,687,035 | -18,435,175 |
