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 2,227,325, 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 | 2,227,325 | |
| -1 | -2,227,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,227,325.
Example:
1 x 2,227,325 = 2,227,325
and
-1 x -2,227,325 = 2,227,325
Notice both answers equal 2,227,325
With that explanation out of the way, let's continue. Next, we take the number 2,227,325 and divide it by 2:
2,227,325 ÷ 2 = 1,113,662.5
If the quotient is a whole number, then 2 and 1,113,662.5 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 | 2,227,325 | |
| -1 | -2,227,325 |
Now, we try dividing 2,227,325 by 3:
2,227,325 ÷ 3 = 742,441.6667
If the quotient is a whole number, then 3 and 742,441.6667 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 | 2,227,325 | |
| -1 | -2,227,325 |
Let's try dividing by 4:
2,227,325 ÷ 4 = 556,831.25
If the quotient is a whole number, then 4 and 556,831.25 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 | 2,227,325 | |
| -1 | 2,227,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 41 | 53 | 205 | 265 | 1,025 | 1,325 | 1,681 | 2,173 | 8,405 | 10,865 | 42,025 | 54,325 | 89,093 | 445,465 | 2,227,325 |
| -1 | -5 | -25 | -41 | -53 | -205 | -265 | -1,025 | -1,325 | -1,681 | -2,173 | -8,405 | -10,865 | -42,025 | -54,325 | -89,093 | -445,465 | -2,227,325 |
