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 105,155,063, 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 | 105,155,063 | |
| -1 | -105,155,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 105,155,063.
Example:
1 x 105,155,063 = 105,155,063
and
-1 x -105,155,063 = 105,155,063
Notice both answers equal 105,155,063
With that explanation out of the way, let's continue. Next, we take the number 105,155,063 and divide it by 2:
105,155,063 ÷ 2 = 52,577,531.5
If the quotient is a whole number, then 2 and 52,577,531.5 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 | 105,155,063 | |
| -1 | -105,155,063 |
Now, we try dividing 105,155,063 by 3:
105,155,063 ÷ 3 = 35,051,687.6667
If the quotient is a whole number, then 3 and 35,051,687.6667 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 | 105,155,063 | |
| -1 | -105,155,063 |
Let's try dividing by 4:
105,155,063 ÷ 4 = 26,288,765.75
If the quotient is a whole number, then 4 and 26,288,765.75 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 | 105,155,063 | |
| -1 | 105,155,063 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 247 | 293 | 1,453 | 3,809 | 5,567 | 18,889 | 27,607 | 72,371 | 358,891 | 425,729 | 5,534,477 | 8,088,851 | 105,155,063 |
| -1 | -13 | -19 | -247 | -293 | -1,453 | -3,809 | -5,567 | -18,889 | -27,607 | -72,371 | -358,891 | -425,729 | -5,534,477 | -8,088,851 | -105,155,063 |
