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 103,280,327, 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 | 103,280,327 | |
| -1 | -103,280,327 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,280,327.
Example:
1 x 103,280,327 = 103,280,327
and
-1 x -103,280,327 = 103,280,327
Notice both answers equal 103,280,327
With that explanation out of the way, let's continue. Next, we take the number 103,280,327 and divide it by 2:
103,280,327 ÷ 2 = 51,640,163.5
If the quotient is a whole number, then 2 and 51,640,163.5 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 | 103,280,327 | |
| -1 | -103,280,327 |
Now, we try dividing 103,280,327 by 3:
103,280,327 ÷ 3 = 34,426,775.6667
If the quotient is a whole number, then 3 and 34,426,775.6667 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 | 103,280,327 | |
| -1 | -103,280,327 |
Let's try dividing by 4:
103,280,327 ÷ 4 = 25,820,081.75
If the quotient is a whole number, then 4 and 25,820,081.75 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 | 103,280,327 | |
| -1 | 103,280,327 |
If you did it right, you will end up with this table:
| 1 | 23 | 73 | 137 | 449 | 1,679 | 3,151 | 10,001 | 10,327 | 32,777 | 61,513 | 230,023 | 753,871 | 1,414,799 | 4,490,449 | 103,280,327 |
| -1 | -23 | -73 | -137 | -449 | -1,679 | -3,151 | -10,001 | -10,327 | -32,777 | -61,513 | -230,023 | -753,871 | -1,414,799 | -4,490,449 | -103,280,327 |
