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 201,441,211, 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 | 201,441,211 | |
| -1 | -201,441,211 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 201,441,211.
Example:
1 x 201,441,211 = 201,441,211
and
-1 x -201,441,211 = 201,441,211
Notice both answers equal 201,441,211
With that explanation out of the way, let's continue. Next, we take the number 201,441,211 and divide it by 2:
201,441,211 ÷ 2 = 100,720,605.5
If the quotient is a whole number, then 2 and 100,720,605.5 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 | 201,441,211 | |
| -1 | -201,441,211 |
Now, we try dividing 201,441,211 by 3:
201,441,211 ÷ 3 = 67,147,070.3333
If the quotient is a whole number, then 3 and 67,147,070.3333 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 | 201,441,211 | |
| -1 | -201,441,211 |
Let's try dividing by 4:
201,441,211 ÷ 4 = 50,360,302.75
If the quotient is a whole number, then 4 and 50,360,302.75 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 | 201,441,211 | |
| -1 | 201,441,211 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 323 | 431 | 1,447 | 7,327 | 8,189 | 24,599 | 27,493 | 139,213 | 467,381 | 623,657 | 10,602,169 | 11,849,483 | 201,441,211 |
| -1 | -17 | -19 | -323 | -431 | -1,447 | -7,327 | -8,189 | -24,599 | -27,493 | -139,213 | -467,381 | -623,657 | -10,602,169 | -11,849,483 | -201,441,211 |
