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 105,660,763, 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 | 105,660,763 | |
| -1 | -105,660,763 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 105,660,763.
Example:
1 x 105,660,763 = 105,660,763
and
-1 x -105,660,763 = 105,660,763
Notice both answers equal 105,660,763
With that explanation out of the way, let's continue. Next, we take the number 105,660,763 and divide it by 2:
105,660,763 ÷ 2 = 52,830,381.5
If the quotient is a whole number, then 2 and 52,830,381.5 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 | 105,660,763 | |
| -1 | -105,660,763 |
Now, we try dividing 105,660,763 by 3:
105,660,763 ÷ 3 = 35,220,254.3333
If the quotient is a whole number, then 3 and 35,220,254.3333 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 | 105,660,763 | |
| -1 | -105,660,763 |
Let's try dividing by 4:
105,660,763 ÷ 4 = 26,415,190.75
If the quotient is a whole number, then 4 and 26,415,190.75 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 | 105,660,763 | |
| -1 | 105,660,763 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 113 | 221 | 1,469 | 1,921 | 4,231 | 24,973 | 55,003 | 71,927 | 478,103 | 935,051 | 6,215,339 | 8,127,751 | 105,660,763 |
| -1 | -13 | -17 | -113 | -221 | -1,469 | -1,921 | -4,231 | -24,973 | -55,003 | -71,927 | -478,103 | -935,051 | -6,215,339 | -8,127,751 | -105,660,763 |
