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 52,000,039, 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 | 52,000,039 | |
| -1 | -52,000,039 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 52,000,039.
Example:
1 x 52,000,039 = 52,000,039
and
-1 x -52,000,039 = 52,000,039
Notice both answers equal 52,000,039
With that explanation out of the way, let's continue. Next, we take the number 52,000,039 and divide it by 2:
52,000,039 ÷ 2 = 26,000,019.5
If the quotient is a whole number, then 2 and 26,000,019.5 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 | 52,000,039 | |
| -1 | -52,000,039 |
Now, we try dividing 52,000,039 by 3:
52,000,039 ÷ 3 = 17,333,346.3333
If the quotient is a whole number, then 3 and 17,333,346.3333 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 | 52,000,039 | |
| -1 | -52,000,039 |
Let's try dividing by 4:
52,000,039 ÷ 4 = 13,000,009.75
If the quotient is a whole number, then 4 and 13,000,009.75 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 | 52,000,039 | |
| -1 | 52,000,039 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 139 | 973 | 1,807 | 4,111 | 12,649 | 28,777 | 53,443 | 374,101 | 571,429 | 4,000,003 | 7,428,577 | 52,000,039 |
| -1 | -7 | -13 | -91 | -139 | -973 | -1,807 | -4,111 | -12,649 | -28,777 | -53,443 | -374,101 | -571,429 | -4,000,003 | -7,428,577 | -52,000,039 |
