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 17,018,225, 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 | 17,018,225 | |
| -1 | -17,018,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,018,225.
Example:
1 x 17,018,225 = 17,018,225
and
-1 x -17,018,225 = 17,018,225
Notice both answers equal 17,018,225
With that explanation out of the way, let's continue. Next, we take the number 17,018,225 and divide it by 2:
17,018,225 ÷ 2 = 8,509,112.5
If the quotient is a whole number, then 2 and 8,509,112.5 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 | 17,018,225 | |
| -1 | -17,018,225 |
Now, we try dividing 17,018,225 by 3:
17,018,225 ÷ 3 = 5,672,741.6667
If the quotient is a whole number, then 3 and 5,672,741.6667 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 | 17,018,225 | |
| -1 | -17,018,225 |
Let's try dividing by 4:
17,018,225 ÷ 4 = 4,254,556.25
If the quotient is a whole number, then 4 and 4,254,556.25 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 | 17,018,225 | |
| -1 | 17,018,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 31 | 35 | 155 | 175 | 217 | 775 | 1,085 | 3,137 | 5,425 | 15,685 | 21,959 | 78,425 | 97,247 | 109,795 | 486,235 | 548,975 | 680,729 | 2,431,175 | 3,403,645 | 17,018,225 |
| -1 | -5 | -7 | -25 | -31 | -35 | -155 | -175 | -217 | -775 | -1,085 | -3,137 | -5,425 | -15,685 | -21,959 | -78,425 | -97,247 | -109,795 | -486,235 | -548,975 | -680,729 | -2,431,175 | -3,403,645 | -17,018,225 |
