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 51,253,325, 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 | 51,253,325 | |
| -1 | -51,253,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,253,325.
Example:
1 x 51,253,325 = 51,253,325
and
-1 x -51,253,325 = 51,253,325
Notice both answers equal 51,253,325
With that explanation out of the way, let's continue. Next, we take the number 51,253,325 and divide it by 2:
51,253,325 ÷ 2 = 25,626,662.5
If the quotient is a whole number, then 2 and 25,626,662.5 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 | 51,253,325 | |
| -1 | -51,253,325 |
Now, we try dividing 51,253,325 by 3:
51,253,325 ÷ 3 = 17,084,441.6667
If the quotient is a whole number, then 3 and 17,084,441.6667 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 | 51,253,325 | |
| -1 | -51,253,325 |
Let's try dividing by 4:
51,253,325 ÷ 4 = 12,813,331.25
If the quotient is a whole number, then 4 and 12,813,331.25 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 | 51,253,325 | |
| -1 | 51,253,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 37 | 67 | 185 | 335 | 827 | 925 | 1,675 | 2,479 | 4,135 | 12,395 | 20,675 | 30,599 | 55,409 | 61,975 | 152,995 | 277,045 | 764,975 | 1,385,225 | 2,050,133 | 10,250,665 | 51,253,325 |
| -1 | -5 | -25 | -37 | -67 | -185 | -335 | -827 | -925 | -1,675 | -2,479 | -4,135 | -12,395 | -20,675 | -30,599 | -55,409 | -61,975 | -152,995 | -277,045 | -764,975 | -1,385,225 | -2,050,133 | -10,250,665 | -51,253,325 |
