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 222,050,543, 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 | 222,050,543 | |
| -1 | -222,050,543 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,050,543.
Example:
1 x 222,050,543 = 222,050,543
and
-1 x -222,050,543 = 222,050,543
Notice both answers equal 222,050,543
With that explanation out of the way, let's continue. Next, we take the number 222,050,543 and divide it by 2:
222,050,543 ÷ 2 = 111,025,271.5
If the quotient is a whole number, then 2 and 111,025,271.5 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 | 222,050,543 | |
| -1 | -222,050,543 |
Now, we try dividing 222,050,543 by 3:
222,050,543 ÷ 3 = 74,016,847.6667
If the quotient is a whole number, then 3 and 74,016,847.6667 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 | 222,050,543 | |
| -1 | -222,050,543 |
Let's try dividing by 4:
222,050,543 ÷ 4 = 55,512,635.75
If the quotient is a whole number, then 4 and 55,512,635.75 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 | 222,050,543 | |
| -1 | 222,050,543 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 569 | 2,729 | 6,259 | 7,397 | 30,019 | 35,477 | 81,367 | 390,247 | 1,552,801 | 17,080,811 | 20,186,413 | 222,050,543 |
| -1 | -11 | -13 | -143 | -569 | -2,729 | -6,259 | -7,397 | -30,019 | -35,477 | -81,367 | -390,247 | -1,552,801 | -17,080,811 | -20,186,413 | -222,050,543 |
