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 222,153,235, 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 | 222,153,235 | |
| -1 | -222,153,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,153,235.
Example:
1 x 222,153,235 = 222,153,235
and
-1 x -222,153,235 = 222,153,235
Notice both answers equal 222,153,235
With that explanation out of the way, let's continue. Next, we take the number 222,153,235 and divide it by 2:
222,153,235 ÷ 2 = 111,076,617.5
If the quotient is a whole number, then 2 and 111,076,617.5 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 | 222,153,235 | |
| -1 | -222,153,235 |
Now, we try dividing 222,153,235 by 3:
222,153,235 ÷ 3 = 74,051,078.3333
If the quotient is a whole number, then 3 and 74,051,078.3333 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 | 222,153,235 | |
| -1 | -222,153,235 |
Let's try dividing by 4:
222,153,235 ÷ 4 = 55,538,308.75
If the quotient is a whole number, then 4 and 55,538,308.75 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 | 222,153,235 | |
| -1 | 222,153,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 83 | 365 | 415 | 6,059 | 7,333 | 30,295 | 36,665 | 535,309 | 608,639 | 2,676,545 | 3,043,195 | 44,430,647 | 222,153,235 |
| -1 | -5 | -73 | -83 | -365 | -415 | -6,059 | -7,333 | -30,295 | -36,665 | -535,309 | -608,639 | -2,676,545 | -3,043,195 | -44,430,647 | -222,153,235 |
