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 110,110,615, 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 | 110,110,615 | |
| -1 | -110,110,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 110,110,615.
Example:
1 x 110,110,615 = 110,110,615
and
-1 x -110,110,615 = 110,110,615
Notice both answers equal 110,110,615
With that explanation out of the way, let's continue. Next, we take the number 110,110,615 and divide it by 2:
110,110,615 ÷ 2 = 55,055,307.5
If the quotient is a whole number, then 2 and 55,055,307.5 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 | 110,110,615 | |
| -1 | -110,110,615 |
Now, we try dividing 110,110,615 by 3:
110,110,615 ÷ 3 = 36,703,538.3333
If the quotient is a whole number, then 3 and 36,703,538.3333 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 | 110,110,615 | |
| -1 | -110,110,615 |
Let's try dividing by 4:
110,110,615 ÷ 4 = 27,527,653.75
If the quotient is a whole number, then 4 and 27,527,653.75 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 | 110,110,615 | |
| -1 | 110,110,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 167 | 835 | 2,839 | 7,757 | 14,195 | 38,785 | 131,869 | 659,345 | 1,295,419 | 6,477,095 | 22,022,123 | 110,110,615 |
| -1 | -5 | -17 | -85 | -167 | -835 | -2,839 | -7,757 | -14,195 | -38,785 | -131,869 | -659,345 | -1,295,419 | -6,477,095 | -22,022,123 | -110,110,615 |
