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 222,775, 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 | 222,775 | |
| -1 | -222,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,775.
Example:
1 x 222,775 = 222,775
and
-1 x -222,775 = 222,775
Notice both answers equal 222,775
With that explanation out of the way, let's continue. Next, we take the number 222,775 and divide it by 2:
222,775 ÷ 2 = 111,387.5
If the quotient is a whole number, then 2 and 111,387.5 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 | 222,775 | |
| -1 | -222,775 |
Now, we try dividing 222,775 by 3:
222,775 ÷ 3 = 74,258.3333
If the quotient is a whole number, then 3 and 74,258.3333 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 | 222,775 | |
| -1 | -222,775 |
Let's try dividing by 4:
222,775 ÷ 4 = 55,693.75
If the quotient is a whole number, then 4 and 55,693.75 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 | 222,775 | |
| -1 | 222,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 25 | 35 | 67 | 95 | 133 | 175 | 335 | 469 | 475 | 665 | 1,273 | 1,675 | 2,345 | 3,325 | 6,365 | 8,911 | 11,725 | 31,825 | 44,555 | 222,775 |
| -1 | -5 | -7 | -19 | -25 | -35 | -67 | -95 | -133 | -175 | -335 | -469 | -475 | -665 | -1,273 | -1,675 | -2,345 | -3,325 | -6,365 | -8,911 | -11,725 | -31,825 | -44,555 | -222,775 |
