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 51,325,235, 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 | 51,325,235 | |
| -1 | -51,325,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,325,235.
Example:
1 x 51,325,235 = 51,325,235
and
-1 x -51,325,235 = 51,325,235
Notice both answers equal 51,325,235
With that explanation out of the way, let's continue. Next, we take the number 51,325,235 and divide it by 2:
51,325,235 ÷ 2 = 25,662,617.5
If the quotient is a whole number, then 2 and 25,662,617.5 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 | 51,325,235 | |
| -1 | -51,325,235 |
Now, we try dividing 51,325,235 by 3:
51,325,235 ÷ 3 = 17,108,411.6667
If the quotient is a whole number, then 3 and 17,108,411.6667 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 | 51,325,235 | |
| -1 | -51,325,235 |
Let's try dividing by 4:
51,325,235 ÷ 4 = 12,831,308.75
If the quotient is a whole number, then 4 and 12,831,308.75 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 | 51,325,235 | |
| -1 | 51,325,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 41 | 65 | 205 | 533 | 2,665 | 19,259 | 96,295 | 250,367 | 789,619 | 1,251,835 | 3,948,095 | 10,265,047 | 51,325,235 |
| -1 | -5 | -13 | -41 | -65 | -205 | -533 | -2,665 | -19,259 | -96,295 | -250,367 | -789,619 | -1,251,835 | -3,948,095 | -10,265,047 | -51,325,235 |
