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 51,625,039, 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 | 51,625,039 | |
| -1 | -51,625,039 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,625,039.
Example:
1 x 51,625,039 = 51,625,039
and
-1 x -51,625,039 = 51,625,039
Notice both answers equal 51,625,039
With that explanation out of the way, let's continue. Next, we take the number 51,625,039 and divide it by 2:
51,625,039 ÷ 2 = 25,812,519.5
If the quotient is a whole number, then 2 and 25,812,519.5 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 | 51,625,039 | |
| -1 | -51,625,039 |
Now, we try dividing 51,625,039 by 3:
51,625,039 ÷ 3 = 17,208,346.3333
If the quotient is a whole number, then 3 and 17,208,346.3333 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 | 51,625,039 | |
| -1 | -51,625,039 |
Let's try dividing by 4:
51,625,039 ÷ 4 = 12,906,259.75
If the quotient is a whole number, then 4 and 12,906,259.75 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 | 51,625,039 | |
| -1 | 51,625,039 |
If you did it right, you will end up with this table:
| 1 | 17 | 101 | 107 | 281 | 1,717 | 1,819 | 4,777 | 10,807 | 28,381 | 30,067 | 183,719 | 482,477 | 511,139 | 3,036,767 | 51,625,039 |
| -1 | -17 | -101 | -107 | -281 | -1,717 | -1,819 | -4,777 | -10,807 | -28,381 | -30,067 | -183,719 | -482,477 | -511,139 | -3,036,767 | -51,625,039 |
