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 51,982,675, 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 | 51,982,675 | |
| -1 | -51,982,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,982,675.
Example:
1 x 51,982,675 = 51,982,675
and
-1 x -51,982,675 = 51,982,675
Notice both answers equal 51,982,675
With that explanation out of the way, let's continue. Next, we take the number 51,982,675 and divide it by 2:
51,982,675 ÷ 2 = 25,991,337.5
If the quotient is a whole number, then 2 and 25,991,337.5 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 | 51,982,675 | |
| -1 | -51,982,675 |
Now, we try dividing 51,982,675 by 3:
51,982,675 ÷ 3 = 17,327,558.3333
If the quotient is a whole number, then 3 and 17,327,558.3333 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 | 51,982,675 | |
| -1 | -51,982,675 |
Let's try dividing by 4:
51,982,675 ÷ 4 = 12,995,668.75
If the quotient is a whole number, then 4 and 12,995,668.75 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 | 51,982,675 | |
| -1 | 51,982,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 61 | 89 | 305 | 383 | 445 | 1,525 | 1,915 | 2,225 | 5,429 | 9,575 | 23,363 | 27,145 | 34,087 | 116,815 | 135,725 | 170,435 | 584,075 | 852,175 | 2,079,307 | 10,396,535 | 51,982,675 |
| -1 | -5 | -25 | -61 | -89 | -305 | -383 | -445 | -1,525 | -1,915 | -2,225 | -5,429 | -9,575 | -23,363 | -27,145 | -34,087 | -116,815 | -135,725 | -170,435 | -584,075 | -852,175 | -2,079,307 | -10,396,535 | -51,982,675 |
