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 52,147,205, 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 | 52,147,205 | |
| -1 | -52,147,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 52,147,205.
Example:
1 x 52,147,205 = 52,147,205
and
-1 x -52,147,205 = 52,147,205
Notice both answers equal 52,147,205
With that explanation out of the way, let's continue. Next, we take the number 52,147,205 and divide it by 2:
52,147,205 ÷ 2 = 26,073,602.5
If the quotient is a whole number, then 2 and 26,073,602.5 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 | 52,147,205 | |
| -1 | -52,147,205 |
Now, we try dividing 52,147,205 by 3:
52,147,205 ÷ 3 = 17,382,401.6667
If the quotient is a whole number, then 3 and 17,382,401.6667 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 | 52,147,205 | |
| -1 | -52,147,205 |
Let's try dividing by 4:
52,147,205 ÷ 4 = 13,036,801.25
If the quotient is a whole number, then 4 and 13,036,801.25 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 | 52,147,205 | |
| -1 | 52,147,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 47 | 55 | 235 | 517 | 2,585 | 20,173 | 100,865 | 221,903 | 948,131 | 1,109,515 | 4,740,655 | 10,429,441 | 52,147,205 |
| -1 | -5 | -11 | -47 | -55 | -235 | -517 | -2,585 | -20,173 | -100,865 | -221,903 | -948,131 | -1,109,515 | -4,740,655 | -10,429,441 | -52,147,205 |
