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 1,198,225, 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 | 1,198,225 | |
| -1 | -1,198,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,198,225.
Example:
1 x 1,198,225 = 1,198,225
and
-1 x -1,198,225 = 1,198,225
Notice both answers equal 1,198,225
With that explanation out of the way, let's continue. Next, we take the number 1,198,225 and divide it by 2:
1,198,225 ÷ 2 = 599,112.5
If the quotient is a whole number, then 2 and 599,112.5 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 | 1,198,225 | |
| -1 | -1,198,225 |
Now, we try dividing 1,198,225 by 3:
1,198,225 ÷ 3 = 399,408.3333
If the quotient is a whole number, then 3 and 399,408.3333 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 | 1,198,225 | |
| -1 | -1,198,225 |
Let's try dividing by 4:
1,198,225 ÷ 4 = 299,556.25
If the quotient is a whole number, then 4 and 299,556.25 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 | 1,198,225 | |
| -1 | 1,198,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 41 | 167 | 175 | 205 | 287 | 835 | 1,025 | 1,169 | 1,435 | 4,175 | 5,845 | 6,847 | 7,175 | 29,225 | 34,235 | 47,929 | 171,175 | 239,645 | 1,198,225 |
| -1 | -5 | -7 | -25 | -35 | -41 | -167 | -175 | -205 | -287 | -835 | -1,025 | -1,169 | -1,435 | -4,175 | -5,845 | -6,847 | -7,175 | -29,225 | -34,235 | -47,929 | -171,175 | -239,645 | -1,198,225 |
