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 102,252,851, 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 | 102,252,851 | |
| -1 | -102,252,851 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,252,851.
Example:
1 x 102,252,851 = 102,252,851
and
-1 x -102,252,851 = 102,252,851
Notice both answers equal 102,252,851
With that explanation out of the way, let's continue. Next, we take the number 102,252,851 and divide it by 2:
102,252,851 ÷ 2 = 51,126,425.5
If the quotient is a whole number, then 2 and 51,126,425.5 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 | 102,252,851 | |
| -1 | -102,252,851 |
Now, we try dividing 102,252,851 by 3:
102,252,851 ÷ 3 = 34,084,283.6667
If the quotient is a whole number, then 3 and 34,084,283.6667 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 | 102,252,851 | |
| -1 | -102,252,851 |
Let's try dividing by 4:
102,252,851 ÷ 4 = 25,563,212.75
If the quotient is a whole number, then 4 and 25,563,212.75 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 | 102,252,851 | |
| -1 | 102,252,851 |
If you did it right, you will end up with this table:
| 1 | 19 | 71 | 229 | 331 | 1,349 | 4,351 | 6,289 | 16,259 | 23,501 | 75,799 | 308,921 | 446,519 | 1,440,181 | 5,381,729 | 102,252,851 |
| -1 | -19 | -71 | -229 | -331 | -1,349 | -4,351 | -6,289 | -16,259 | -23,501 | -75,799 | -308,921 | -446,519 | -1,440,181 | -5,381,729 | -102,252,851 |
