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 222,105,545, 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 | 222,105,545 | |
| -1 | -222,105,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,105,545.
Example:
1 x 222,105,545 = 222,105,545
and
-1 x -222,105,545 = 222,105,545
Notice both answers equal 222,105,545
With that explanation out of the way, let's continue. Next, we take the number 222,105,545 and divide it by 2:
222,105,545 ÷ 2 = 111,052,772.5
If the quotient is a whole number, then 2 and 111,052,772.5 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 | 222,105,545 | |
| -1 | -222,105,545 |
Now, we try dividing 222,105,545 by 3:
222,105,545 ÷ 3 = 74,035,181.6667
If the quotient is a whole number, then 3 and 74,035,181.6667 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 | 222,105,545 | |
| -1 | -222,105,545 |
Let's try dividing by 4:
222,105,545 ÷ 4 = 55,526,386.25
If the quotient is a whole number, then 4 and 55,526,386.25 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 | 222,105,545 | |
| -1 | 222,105,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 157 | 785 | 4,867 | 9,127 | 24,335 | 45,635 | 282,937 | 1,414,685 | 1,432,939 | 7,164,695 | 44,421,109 | 222,105,545 |
| -1 | -5 | -31 | -155 | -157 | -785 | -4,867 | -9,127 | -24,335 | -45,635 | -282,937 | -1,414,685 | -1,432,939 | -7,164,695 | -44,421,109 | -222,105,545 |
