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 51,323,125, 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 | 51,323,125 | |
| -1 | -51,323,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,323,125.
Example:
1 x 51,323,125 = 51,323,125
and
-1 x -51,323,125 = 51,323,125
Notice both answers equal 51,323,125
With that explanation out of the way, let's continue. Next, we take the number 51,323,125 and divide it by 2:
51,323,125 ÷ 2 = 25,661,562.5
If the quotient is a whole number, then 2 and 25,661,562.5 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 | 51,323,125 | |
| -1 | -51,323,125 |
Now, we try dividing 51,323,125 by 3:
51,323,125 ÷ 3 = 17,107,708.3333
If the quotient is a whole number, then 3 and 17,107,708.3333 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 | 51,323,125 | |
| -1 | -51,323,125 |
Let's try dividing by 4:
51,323,125 ÷ 4 = 12,830,781.25
If the quotient is a whole number, then 4 and 12,830,781.25 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 | 51,323,125 | |
| -1 | 51,323,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 625 | 875 | 4,375 | 11,731 | 58,655 | 82,117 | 293,275 | 410,585 | 1,466,375 | 2,052,925 | 7,331,875 | 10,264,625 | 51,323,125 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -625 | -875 | -4,375 | -11,731 | -58,655 | -82,117 | -293,275 | -410,585 | -1,466,375 | -2,052,925 | -7,331,875 | -10,264,625 | -51,323,125 |
