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 52,123,121, 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 | 52,123,121 | |
| -1 | -52,123,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 52,123,121.
Example:
1 x 52,123,121 = 52,123,121
and
-1 x -52,123,121 = 52,123,121
Notice both answers equal 52,123,121
With that explanation out of the way, let's continue. Next, we take the number 52,123,121 and divide it by 2:
52,123,121 ÷ 2 = 26,061,560.5
If the quotient is a whole number, then 2 and 26,061,560.5 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 | 52,123,121 | |
| -1 | -52,123,121 |
Now, we try dividing 52,123,121 by 3:
52,123,121 ÷ 3 = 17,374,373.6667
If the quotient is a whole number, then 3 and 17,374,373.6667 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 | 52,123,121 | |
| -1 | -52,123,121 |
Let's try dividing by 4:
52,123,121 ÷ 4 = 13,030,780.25
If the quotient is a whole number, then 4 and 13,030,780.25 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 | 52,123,121 | |
| -1 | 52,123,121 |
If you did it right, you will end up with this table:
| 1 | 29 | 31 | 37 | 899 | 1,073 | 1,147 | 1,567 | 33,263 | 45,443 | 48,577 | 57,979 | 1,408,733 | 1,681,391 | 1,797,349 | 52,123,121 |
| -1 | -29 | -31 | -37 | -899 | -1,073 | -1,147 | -1,567 | -33,263 | -45,443 | -48,577 | -57,979 | -1,408,733 | -1,681,391 | -1,797,349 | -52,123,121 |
