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 211,323,301, 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 | 211,323,301 | |
| -1 | -211,323,301 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 211,323,301.
Example:
1 x 211,323,301 = 211,323,301
and
-1 x -211,323,301 = 211,323,301
Notice both answers equal 211,323,301
With that explanation out of the way, let's continue. Next, we take the number 211,323,301 and divide it by 2:
211,323,301 ÷ 2 = 105,661,650.5
If the quotient is a whole number, then 2 and 105,661,650.5 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 | 211,323,301 | |
| -1 | -211,323,301 |
Now, we try dividing 211,323,301 by 3:
211,323,301 ÷ 3 = 70,441,100.3333
If the quotient is a whole number, then 3 and 70,441,100.3333 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 | 211,323,301 | |
| -1 | -211,323,301 |
Let's try dividing by 4:
211,323,301 ÷ 4 = 52,830,825.25
If the quotient is a whole number, then 4 and 52,830,825.25 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 | 211,323,301 | |
| -1 | 211,323,301 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 127 | 133 | 889 | 2,413 | 12,511 | 16,891 | 87,577 | 237,709 | 1,588,897 | 1,663,963 | 11,122,279 | 30,189,043 | 211,323,301 |
| -1 | -7 | -19 | -127 | -133 | -889 | -2,413 | -12,511 | -16,891 | -87,577 | -237,709 | -1,588,897 | -1,663,963 | -11,122,279 | -30,189,043 | -211,323,301 |
