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 51,980,903, 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 | 51,980,903 | |
| -1 | -51,980,903 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,980,903.
Example:
1 x 51,980,903 = 51,980,903
and
-1 x -51,980,903 = 51,980,903
Notice both answers equal 51,980,903
With that explanation out of the way, let's continue. Next, we take the number 51,980,903 and divide it by 2:
51,980,903 ÷ 2 = 25,990,451.5
If the quotient is a whole number, then 2 and 25,990,451.5 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 | 51,980,903 | |
| -1 | -51,980,903 |
Now, we try dividing 51,980,903 by 3:
51,980,903 ÷ 3 = 17,326,967.6667
If the quotient is a whole number, then 3 and 17,326,967.6667 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 | 51,980,903 | |
| -1 | -51,980,903 |
Let's try dividing by 4:
51,980,903 ÷ 4 = 12,995,225.75
If the quotient is a whole number, then 4 and 12,995,225.75 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 | 51,980,903 | |
| -1 | 51,980,903 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 247 | 389 | 541 | 5,057 | 7,033 | 7,391 | 10,279 | 96,083 | 133,627 | 210,449 | 2,735,837 | 3,998,531 | 51,980,903 |
| -1 | -13 | -19 | -247 | -389 | -541 | -5,057 | -7,033 | -7,391 | -10,279 | -96,083 | -133,627 | -210,449 | -2,735,837 | -3,998,531 | -51,980,903 |
