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 51,821,965, 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 | 51,821,965 | |
| -1 | -51,821,965 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,821,965.
Example:
1 x 51,821,965 = 51,821,965
and
-1 x -51,821,965 = 51,821,965
Notice both answers equal 51,821,965
With that explanation out of the way, let's continue. Next, we take the number 51,821,965 and divide it by 2:
51,821,965 ÷ 2 = 25,910,982.5
If the quotient is a whole number, then 2 and 25,910,982.5 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 | 51,821,965 | |
| -1 | -51,821,965 |
Now, we try dividing 51,821,965 by 3:
51,821,965 ÷ 3 = 17,273,988.3333
If the quotient is a whole number, then 3 and 17,273,988.3333 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 | 51,821,965 | |
| -1 | -51,821,965 |
Let's try dividing by 4:
51,821,965 ÷ 4 = 12,955,491.25
If the quotient is a whole number, then 4 and 12,955,491.25 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 | 51,821,965 | |
| -1 | 51,821,965 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 47 | 65 | 235 | 611 | 3,055 | 16,963 | 84,815 | 220,519 | 797,261 | 1,102,595 | 3,986,305 | 10,364,393 | 51,821,965 |
| -1 | -5 | -13 | -47 | -65 | -235 | -611 | -3,055 | -16,963 | -84,815 | -220,519 | -797,261 | -1,102,595 | -3,986,305 | -10,364,393 | -51,821,965 |
