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 102,450,365, 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 | 102,450,365 | |
| -1 | -102,450,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,450,365.
Example:
1 x 102,450,365 = 102,450,365
and
-1 x -102,450,365 = 102,450,365
Notice both answers equal 102,450,365
With that explanation out of the way, let's continue. Next, we take the number 102,450,365 and divide it by 2:
102,450,365 ÷ 2 = 51,225,182.5
If the quotient is a whole number, then 2 and 51,225,182.5 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 | 102,450,365 | |
| -1 | -102,450,365 |
Now, we try dividing 102,450,365 by 3:
102,450,365 ÷ 3 = 34,150,121.6667
If the quotient is a whole number, then 3 and 34,150,121.6667 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 | 102,450,365 | |
| -1 | -102,450,365 |
Let's try dividing by 4:
102,450,365 ÷ 4 = 25,612,591.25
If the quotient is a whole number, then 4 and 25,612,591.25 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 | 102,450,365 | |
| -1 | 102,450,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 235 | 547 | 797 | 2,735 | 3,985 | 25,709 | 37,459 | 128,545 | 187,295 | 435,959 | 2,179,795 | 20,490,073 | 102,450,365 |
| -1 | -5 | -47 | -235 | -547 | -797 | -2,735 | -3,985 | -25,709 | -37,459 | -128,545 | -187,295 | -435,959 | -2,179,795 | -20,490,073 | -102,450,365 |
