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 105,555,043, 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 | 105,555,043 | |
| -1 | -105,555,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 105,555,043.
Example:
1 x 105,555,043 = 105,555,043
and
-1 x -105,555,043 = 105,555,043
Notice both answers equal 105,555,043
With that explanation out of the way, let's continue. Next, we take the number 105,555,043 and divide it by 2:
105,555,043 ÷ 2 = 52,777,521.5
If the quotient is a whole number, then 2 and 52,777,521.5 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 | 105,555,043 | |
| -1 | -105,555,043 |
Now, we try dividing 105,555,043 by 3:
105,555,043 ÷ 3 = 35,185,014.3333
If the quotient is a whole number, then 3 and 35,185,014.3333 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 | 105,555,043 | |
| -1 | -105,555,043 |
Let's try dividing by 4:
105,555,043 ÷ 4 = 26,388,760.75
If the quotient is a whole number, then 4 and 26,388,760.75 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 | 105,555,043 | |
| -1 | 105,555,043 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 223 | 407 | 1,163 | 2,453 | 8,251 | 12,793 | 43,031 | 90,761 | 259,349 | 473,341 | 2,852,839 | 9,595,913 | 105,555,043 |
| -1 | -11 | -37 | -223 | -407 | -1,163 | -2,453 | -8,251 | -12,793 | -43,031 | -90,761 | -259,349 | -473,341 | -2,852,839 | -9,595,913 | -105,555,043 |
