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 222,162,499, 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 | 222,162,499 | |
| -1 | -222,162,499 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,162,499.
Example:
1 x 222,162,499 = 222,162,499
and
-1 x -222,162,499 = 222,162,499
Notice both answers equal 222,162,499
With that explanation out of the way, let's continue. Next, we take the number 222,162,499 and divide it by 2:
222,162,499 ÷ 2 = 111,081,249.5
If the quotient is a whole number, then 2 and 111,081,249.5 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 | 222,162,499 | |
| -1 | -222,162,499 |
Now, we try dividing 222,162,499 by 3:
222,162,499 ÷ 3 = 74,054,166.3333
If the quotient is a whole number, then 3 and 74,054,166.3333 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 | 222,162,499 | |
| -1 | -222,162,499 |
Let's try dividing by 4:
222,162,499 ÷ 4 = 55,540,624.75
If the quotient is a whole number, then 4 and 55,540,624.75 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 | 222,162,499 | |
| -1 | 222,162,499 |
If you did it right, you will end up with this table:
| 1 | 13 | 169 | 1,314,571 | 17,089,423 | 222,162,499 |
| -1 | -13 | -169 | -1,314,571 | -17,089,423 | -222,162,499 |
