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 222,324,635, 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 | 222,324,635 | |
| -1 | -222,324,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,324,635.
Example:
1 x 222,324,635 = 222,324,635
and
-1 x -222,324,635 = 222,324,635
Notice both answers equal 222,324,635
With that explanation out of the way, let's continue. Next, we take the number 222,324,635 and divide it by 2:
222,324,635 ÷ 2 = 111,162,317.5
If the quotient is a whole number, then 2 and 111,162,317.5 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 | 222,324,635 | |
| -1 | -222,324,635 |
Now, we try dividing 222,324,635 by 3:
222,324,635 ÷ 3 = 74,108,211.6667
If the quotient is a whole number, then 3 and 74,108,211.6667 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 | 222,324,635 | |
| -1 | -222,324,635 |
Let's try dividing by 4:
222,324,635 ÷ 4 = 55,581,158.75
If the quotient is a whole number, then 4 and 55,581,158.75 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 | 222,324,635 | |
| -1 | 222,324,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 347 | 1,735 | 4,511 | 9,857 | 22,555 | 49,285 | 128,141 | 640,705 | 3,420,379 | 17,101,895 | 44,464,927 | 222,324,635 |
| -1 | -5 | -13 | -65 | -347 | -1,735 | -4,511 | -9,857 | -22,555 | -49,285 | -128,141 | -640,705 | -3,420,379 | -17,101,895 | -44,464,927 | -222,324,635 |
