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 222,244,225, 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 | 222,244,225 | |
| -1 | -222,244,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,244,225.
Example:
1 x 222,244,225 = 222,244,225
and
-1 x -222,244,225 = 222,244,225
Notice both answers equal 222,244,225
With that explanation out of the way, let's continue. Next, we take the number 222,244,225 and divide it by 2:
222,244,225 ÷ 2 = 111,122,112.5
If the quotient is a whole number, then 2 and 111,122,112.5 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 | 222,244,225 | |
| -1 | -222,244,225 |
Now, we try dividing 222,244,225 by 3:
222,244,225 ÷ 3 = 74,081,408.3333
If the quotient is a whole number, then 3 and 74,081,408.3333 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 | 222,244,225 | |
| -1 | -222,244,225 |
Let's try dividing by 4:
222,244,225 ÷ 4 = 55,561,056.25
If the quotient is a whole number, then 4 and 55,561,056.25 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 | 222,244,225 | |
| -1 | 222,244,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 401 | 2,005 | 2,807 | 3,167 | 10,025 | 14,035 | 15,835 | 22,169 | 70,175 | 79,175 | 110,845 | 554,225 | 1,269,967 | 6,349,835 | 8,889,769 | 31,749,175 | 44,448,845 | 222,244,225 |
| -1 | -5 | -7 | -25 | -35 | -175 | -401 | -2,005 | -2,807 | -3,167 | -10,025 | -14,035 | -15,835 | -22,169 | -70,175 | -79,175 | -110,845 | -554,225 | -1,269,967 | -6,349,835 | -8,889,769 | -31,749,175 | -44,448,845 | -222,244,225 |
