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 52,325,147, 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 | 52,325,147 | |
| -1 | -52,325,147 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 52,325,147.
Example:
1 x 52,325,147 = 52,325,147
and
-1 x -52,325,147 = 52,325,147
Notice both answers equal 52,325,147
With that explanation out of the way, let's continue. Next, we take the number 52,325,147 and divide it by 2:
52,325,147 ÷ 2 = 26,162,573.5
If the quotient is a whole number, then 2 and 26,162,573.5 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 | 52,325,147 | |
| -1 | -52,325,147 |
Now, we try dividing 52,325,147 by 3:
52,325,147 ÷ 3 = 17,441,715.6667
If the quotient is a whole number, then 3 and 17,441,715.6667 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 | 52,325,147 | |
| -1 | -52,325,147 |
Let's try dividing by 4:
52,325,147 ÷ 4 = 13,081,286.75
If the quotient is a whole number, then 4 and 13,081,286.75 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 | 52,325,147 | |
| -1 | 52,325,147 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 89 | 329 | 623 | 1,787 | 4,183 | 12,509 | 29,281 | 83,989 | 159,043 | 587,923 | 1,113,301 | 7,475,021 | 52,325,147 |
| -1 | -7 | -47 | -89 | -329 | -623 | -1,787 | -4,183 | -12,509 | -29,281 | -83,989 | -159,043 | -587,923 | -1,113,301 | -7,475,021 | -52,325,147 |
