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 1,089,275, 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 | 1,089,275 | |
| -1 | -1,089,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,089,275.
Example:
1 x 1,089,275 = 1,089,275
and
-1 x -1,089,275 = 1,089,275
Notice both answers equal 1,089,275
With that explanation out of the way, let's continue. Next, we take the number 1,089,275 and divide it by 2:
1,089,275 ÷ 2 = 544,637.5
If the quotient is a whole number, then 2 and 544,637.5 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 | 1,089,275 | |
| -1 | -1,089,275 |
Now, we try dividing 1,089,275 by 3:
1,089,275 ÷ 3 = 363,091.6667
If the quotient is a whole number, then 3 and 363,091.6667 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 | 1,089,275 | |
| -1 | -1,089,275 |
Let's try dividing by 4:
1,089,275 ÷ 4 = 272,318.75
If the quotient is a whole number, then 4 and 272,318.75 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 | 1,089,275 | |
| -1 | 1,089,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 25 | 55 | 85 | 187 | 233 | 275 | 425 | 935 | 1,165 | 2,563 | 3,961 | 4,675 | 5,825 | 12,815 | 19,805 | 43,571 | 64,075 | 99,025 | 217,855 | 1,089,275 |
| -1 | -5 | -11 | -17 | -25 | -55 | -85 | -187 | -233 | -275 | -425 | -935 | -1,165 | -2,563 | -3,961 | -4,675 | -5,825 | -12,815 | -19,805 | -43,571 | -64,075 | -99,025 | -217,855 | -1,089,275 |
