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 213,110,029, 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 | 213,110,029 | |
-1 | -213,110,029 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 213,110,029.
Example:
1 x 213,110,029 = 213,110,029
and
-1 x -213,110,029 = 213,110,029
Notice both answers equal 213,110,029
With that explanation out of the way, let's continue. Next, we take the number 213,110,029 and divide it by 2:
213,110,029 ÷ 2 = 106,555,014.5
If the quotient is a whole number, then 2 and 106,555,014.5 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 | 213,110,029 | |
-1 | -213,110,029 |
Now, we try dividing 213,110,029 by 3:
213,110,029 ÷ 3 = 71,036,676.3333
If the quotient is a whole number, then 3 and 71,036,676.3333 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 | 213,110,029 | |
-1 | -213,110,029 |
Let's try dividing by 4:
213,110,029 ÷ 4 = 53,277,507.25
If the quotient is a whole number, then 4 and 53,277,507.25 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 | 213,110,029 | |
-1 | 213,110,029 |
If you did it right, you will end up with this table:
1 | 11 | 19,373,639 | 213,110,029 |
-1 | -11 | -19,373,639 | -213,110,029 |
