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 51,425,869, 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 | 51,425,869 | |
| -1 | -51,425,869 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,425,869.
Example:
1 x 51,425,869 = 51,425,869
and
-1 x -51,425,869 = 51,425,869
Notice both answers equal 51,425,869
With that explanation out of the way, let's continue. Next, we take the number 51,425,869 and divide it by 2:
51,425,869 ÷ 2 = 25,712,934.5
If the quotient is a whole number, then 2 and 25,712,934.5 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 | 51,425,869 | |
| -1 | -51,425,869 |
Now, we try dividing 51,425,869 by 3:
51,425,869 ÷ 3 = 17,141,956.3333
If the quotient is a whole number, then 3 and 17,141,956.3333 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 | 51,425,869 | |
| -1 | -51,425,869 |
Let's try dividing by 4:
51,425,869 ÷ 4 = 12,856,467.25
If the quotient is a whole number, then 4 and 12,856,467.25 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 | 51,425,869 | |
| -1 | 51,425,869 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 239 | 341 | 631 | 2,629 | 6,941 | 7,409 | 19,561 | 81,499 | 150,809 | 215,171 | 1,658,899 | 4,675,079 | 51,425,869 |
| -1 | -11 | -31 | -239 | -341 | -631 | -2,629 | -6,941 | -7,409 | -19,561 | -81,499 | -150,809 | -215,171 | -1,658,899 | -4,675,079 | -51,425,869 |
