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 52,123,513, 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 | 52,123,513 | |
| -1 | -52,123,513 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 52,123,513.
Example:
1 x 52,123,513 = 52,123,513
and
-1 x -52,123,513 = 52,123,513
Notice both answers equal 52,123,513
With that explanation out of the way, let's continue. Next, we take the number 52,123,513 and divide it by 2:
52,123,513 ÷ 2 = 26,061,756.5
If the quotient is a whole number, then 2 and 26,061,756.5 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 | 52,123,513 | |
| -1 | -52,123,513 |
Now, we try dividing 52,123,513 by 3:
52,123,513 ÷ 3 = 17,374,504.3333
If the quotient is a whole number, then 3 and 17,374,504.3333 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 | 52,123,513 | |
| -1 | -52,123,513 |
Let's try dividing by 4:
52,123,513 ÷ 4 = 13,030,878.25
If the quotient is a whole number, then 4 and 13,030,878.25 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 | 52,123,513 | |
| -1 | 52,123,513 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 227 | 1,039 | 2,951 | 3,859 | 13,507 | 17,663 | 50,167 | 229,619 | 235,853 | 3,066,089 | 4,009,501 | 52,123,513 |
| -1 | -13 | -17 | -221 | -227 | -1,039 | -2,951 | -3,859 | -13,507 | -17,663 | -50,167 | -229,619 | -235,853 | -3,066,089 | -4,009,501 | -52,123,513 |
