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 110,587,505, 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 | 110,587,505 | |
| -1 | -110,587,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 110,587,505.
Example:
1 x 110,587,505 = 110,587,505
and
-1 x -110,587,505 = 110,587,505
Notice both answers equal 110,587,505
With that explanation out of the way, let's continue. Next, we take the number 110,587,505 and divide it by 2:
110,587,505 ÷ 2 = 55,293,752.5
If the quotient is a whole number, then 2 and 55,293,752.5 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 | 110,587,505 | |
| -1 | -110,587,505 |
Now, we try dividing 110,587,505 by 3:
110,587,505 ÷ 3 = 36,862,501.6667
If the quotient is a whole number, then 3 and 36,862,501.6667 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 | 110,587,505 | |
| -1 | -110,587,505 |
Let's try dividing by 4:
110,587,505 ÷ 4 = 27,646,876.25
If the quotient is a whole number, then 4 and 27,646,876.25 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 | 110,587,505 | |
| -1 | 110,587,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 166,297 | 831,485 | 1,164,079 | 3,159,643 | 5,820,395 | 15,798,215 | 22,117,501 | 110,587,505 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -166,297 | -831,485 | -1,164,079 | -3,159,643 | -5,820,395 | -15,798,215 | -22,117,501 | -110,587,505 |
