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 51,826,271, 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 | 51,826,271 | |
| -1 | -51,826,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,826,271.
Example:
1 x 51,826,271 = 51,826,271
and
-1 x -51,826,271 = 51,826,271
Notice both answers equal 51,826,271
With that explanation out of the way, let's continue. Next, we take the number 51,826,271 and divide it by 2:
51,826,271 ÷ 2 = 25,913,135.5
If the quotient is a whole number, then 2 and 25,913,135.5 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 | 51,826,271 | |
| -1 | -51,826,271 |
Now, we try dividing 51,826,271 by 3:
51,826,271 ÷ 3 = 17,275,423.6667
If the quotient is a whole number, then 3 and 17,275,423.6667 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 | 51,826,271 | |
| -1 | -51,826,271 |
Let's try dividing by 4:
51,826,271 ÷ 4 = 12,956,567.75
If the quotient is a whole number, then 4 and 12,956,567.75 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 | 51,826,271 | |
| -1 | 51,826,271 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 61 | 343 | 427 | 2,477 | 2,989 | 17,339 | 20,923 | 121,373 | 151,097 | 849,611 | 1,057,679 | 7,403,753 | 51,826,271 |
| -1 | -7 | -49 | -61 | -343 | -427 | -2,477 | -2,989 | -17,339 | -20,923 | -121,373 | -151,097 | -849,611 | -1,057,679 | -7,403,753 | -51,826,271 |
