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 52,072,685, 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 | 52,072,685 | |
| -1 | -52,072,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 52,072,685.
Example:
1 x 52,072,685 = 52,072,685
and
-1 x -52,072,685 = 52,072,685
Notice both answers equal 52,072,685
With that explanation out of the way, let's continue. Next, we take the number 52,072,685 and divide it by 2:
52,072,685 ÷ 2 = 26,036,342.5
If the quotient is a whole number, then 2 and 26,036,342.5 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 | 52,072,685 | |
| -1 | -52,072,685 |
Now, we try dividing 52,072,685 by 3:
52,072,685 ÷ 3 = 17,357,561.6667
If the quotient is a whole number, then 3 and 17,357,561.6667 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 | 52,072,685 | |
| -1 | -52,072,685 |
Let's try dividing by 4:
52,072,685 ÷ 4 = 13,018,171.25
If the quotient is a whole number, then 4 and 13,018,171.25 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 | 52,072,685 | |
| -1 | 52,072,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 263 | 1,315 | 1,841 | 5,657 | 9,205 | 28,285 | 39,599 | 197,995 | 1,487,791 | 7,438,955 | 10,414,537 | 52,072,685 |
| -1 | -5 | -7 | -35 | -263 | -1,315 | -1,841 | -5,657 | -9,205 | -28,285 | -39,599 | -197,995 | -1,487,791 | -7,438,955 | -10,414,537 | -52,072,685 |
