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 211,044,301, 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 | 211,044,301 | |
| -1 | -211,044,301 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 211,044,301.
Example:
1 x 211,044,301 = 211,044,301
and
-1 x -211,044,301 = 211,044,301
Notice both answers equal 211,044,301
With that explanation out of the way, let's continue. Next, we take the number 211,044,301 and divide it by 2:
211,044,301 ÷ 2 = 105,522,150.5
If the quotient is a whole number, then 2 and 105,522,150.5 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 | 211,044,301 | |
| -1 | -211,044,301 |
Now, we try dividing 211,044,301 by 3:
211,044,301 ÷ 3 = 70,348,100.3333
If the quotient is a whole number, then 3 and 70,348,100.3333 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 | 211,044,301 | |
| -1 | -211,044,301 |
Let's try dividing by 4:
211,044,301 ÷ 4 = 52,761,075.25
If the quotient is a whole number, then 4 and 52,761,075.25 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 | 211,044,301 | |
| -1 | 211,044,301 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 223 | 559 | 1,693 | 2,899 | 9,589 | 22,009 | 72,799 | 124,657 | 377,539 | 946,387 | 4,908,007 | 16,234,177 | 211,044,301 |
| -1 | -13 | -43 | -223 | -559 | -1,693 | -2,899 | -9,589 | -22,009 | -72,799 | -124,657 | -377,539 | -946,387 | -4,908,007 | -16,234,177 | -211,044,301 |
