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 222,425, 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 | 222,425 | |
| -1 | -222,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,425.
Example:
1 x 222,425 = 222,425
and
-1 x -222,425 = 222,425
Notice both answers equal 222,425
With that explanation out of the way, let's continue. Next, we take the number 222,425 and divide it by 2:
222,425 ÷ 2 = 111,212.5
If the quotient is a whole number, then 2 and 111,212.5 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 | 222,425 | |
| -1 | -222,425 |
Now, we try dividing 222,425 by 3:
222,425 ÷ 3 = 74,141.6667
If the quotient is a whole number, then 3 and 74,141.6667 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 | 222,425 | |
| -1 | -222,425 |
Let's try dividing by 4:
222,425 ÷ 4 = 55,606.25
If the quotient is a whole number, then 4 and 55,606.25 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 | 222,425 | |
| -1 | 222,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 31 | 35 | 41 | 155 | 175 | 205 | 217 | 287 | 775 | 1,025 | 1,085 | 1,271 | 1,435 | 5,425 | 6,355 | 7,175 | 8,897 | 31,775 | 44,485 | 222,425 |
| -1 | -5 | -7 | -25 | -31 | -35 | -41 | -155 | -175 | -205 | -217 | -287 | -775 | -1,025 | -1,085 | -1,271 | -1,435 | -5,425 | -6,355 | -7,175 | -8,897 | -31,775 | -44,485 | -222,425 |
