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 222,005,635, 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 | 222,005,635 | |
| -1 | -222,005,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,005,635.
Example:
1 x 222,005,635 = 222,005,635
and
-1 x -222,005,635 = 222,005,635
Notice both answers equal 222,005,635
With that explanation out of the way, let's continue. Next, we take the number 222,005,635 and divide it by 2:
222,005,635 ÷ 2 = 111,002,817.5
If the quotient is a whole number, then 2 and 111,002,817.5 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 | 222,005,635 | |
| -1 | -222,005,635 |
Now, we try dividing 222,005,635 by 3:
222,005,635 ÷ 3 = 74,001,878.3333
If the quotient is a whole number, then 3 and 74,001,878.3333 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 | 222,005,635 | |
| -1 | -222,005,635 |
Let's try dividing by 4:
222,005,635 ÷ 4 = 55,501,408.75
If the quotient is a whole number, then 4 and 55,501,408.75 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 | 222,005,635 | |
| -1 | 222,005,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 983 | 2,657 | 4,915 | 13,285 | 16,711 | 45,169 | 83,555 | 225,845 | 2,611,831 | 13,059,155 | 44,401,127 | 222,005,635 |
| -1 | -5 | -17 | -85 | -983 | -2,657 | -4,915 | -13,285 | -16,711 | -45,169 | -83,555 | -225,845 | -2,611,831 | -13,059,155 | -44,401,127 | -222,005,635 |
