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 103,616,105, 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 | 103,616,105 | |
| -1 | -103,616,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,616,105.
Example:
1 x 103,616,105 = 103,616,105
and
-1 x -103,616,105 = 103,616,105
Notice both answers equal 103,616,105
With that explanation out of the way, let's continue. Next, we take the number 103,616,105 and divide it by 2:
103,616,105 ÷ 2 = 51,808,052.5
If the quotient is a whole number, then 2 and 51,808,052.5 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 | 103,616,105 | |
| -1 | -103,616,105 |
Now, we try dividing 103,616,105 by 3:
103,616,105 ÷ 3 = 34,538,701.6667
If the quotient is a whole number, then 3 and 34,538,701.6667 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 | 103,616,105 | |
| -1 | -103,616,105 |
Let's try dividing by 4:
103,616,105 ÷ 4 = 25,904,026.25
If the quotient is a whole number, then 4 and 25,904,026.25 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 | 103,616,105 | |
| -1 | 103,616,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 31 | 85 | 155 | 527 | 2,635 | 39,323 | 196,615 | 668,491 | 1,219,013 | 3,342,455 | 6,095,065 | 20,723,221 | 103,616,105 |
| -1 | -5 | -17 | -31 | -85 | -155 | -527 | -2,635 | -39,323 | -196,615 | -668,491 | -1,219,013 | -3,342,455 | -6,095,065 | -20,723,221 | -103,616,105 |
