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 220,032,227, 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 | 220,032,227 | |
-1 | -220,032,227 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 220,032,227.
Example:
1 x 220,032,227 = 220,032,227
and
-1 x -220,032,227 = 220,032,227
Notice both answers equal 220,032,227
With that explanation out of the way, let's continue. Next, we take the number 220,032,227 and divide it by 2:
220,032,227 ÷ 2 = 110,016,113.5
If the quotient is a whole number, then 2 and 110,016,113.5 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 | 220,032,227 | |
-1 | -220,032,227 |
Now, we try dividing 220,032,227 by 3:
220,032,227 ÷ 3 = 73,344,075.6667
If the quotient is a whole number, then 3 and 73,344,075.6667 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 | 220,032,227 | |
-1 | -220,032,227 |
Let's try dividing by 4:
220,032,227 ÷ 4 = 55,008,056.75
If the quotient is a whole number, then 4 and 55,008,056.75 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 | 220,032,227 | |
-1 | 220,032,227 |
If you did it right, you will end up with this table:
1 | 2,917 | 75,431 | 220,032,227 |
-1 | -2,917 | -75,431 | -220,032,227 |
