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 102,302,125, 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 | 102,302,125 | |
| -1 | -102,302,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,302,125.
Example:
1 x 102,302,125 = 102,302,125
and
-1 x -102,302,125 = 102,302,125
Notice both answers equal 102,302,125
With that explanation out of the way, let's continue. Next, we take the number 102,302,125 and divide it by 2:
102,302,125 ÷ 2 = 51,151,062.5
If the quotient is a whole number, then 2 and 51,151,062.5 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 | 102,302,125 | |
| -1 | -102,302,125 |
Now, we try dividing 102,302,125 by 3:
102,302,125 ÷ 3 = 34,100,708.3333
If the quotient is a whole number, then 3 and 34,100,708.3333 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 | 102,302,125 | |
| -1 | -102,302,125 |
Let's try dividing by 4:
102,302,125 ÷ 4 = 25,575,531.25
If the quotient is a whole number, then 4 and 25,575,531.25 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 | 102,302,125 | |
| -1 | 102,302,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 71 | 125 | 355 | 1,775 | 8,875 | 11,527 | 57,635 | 288,175 | 818,417 | 1,440,875 | 4,092,085 | 20,460,425 | 102,302,125 |
| -1 | -5 | -25 | -71 | -125 | -355 | -1,775 | -8,875 | -11,527 | -57,635 | -288,175 | -818,417 | -1,440,875 | -4,092,085 | -20,460,425 | -102,302,125 |
