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 102,200,315, 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 | 102,200,315 | |
| -1 | -102,200,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,200,315.
Example:
1 x 102,200,315 = 102,200,315
and
-1 x -102,200,315 = 102,200,315
Notice both answers equal 102,200,315
With that explanation out of the way, let's continue. Next, we take the number 102,200,315 and divide it by 2:
102,200,315 ÷ 2 = 51,100,157.5
If the quotient is a whole number, then 2 and 51,100,157.5 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 | 102,200,315 | |
| -1 | -102,200,315 |
Now, we try dividing 102,200,315 by 3:
102,200,315 ÷ 3 = 34,066,771.6667
If the quotient is a whole number, then 3 and 34,066,771.6667 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 | 102,200,315 | |
| -1 | -102,200,315 |
Let's try dividing by 4:
102,200,315 ÷ 4 = 25,550,078.75
If the quotient is a whole number, then 4 and 25,550,078.75 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 | 102,200,315 | |
| -1 | 102,200,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 61 | 305 | 427 | 2,135 | 47,869 | 239,345 | 335,083 | 1,675,415 | 2,920,009 | 14,600,045 | 20,440,063 | 102,200,315 |
| -1 | -5 | -7 | -35 | -61 | -305 | -427 | -2,135 | -47,869 | -239,345 | -335,083 | -1,675,415 | -2,920,009 | -14,600,045 | -20,440,063 | -102,200,315 |
