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 103,543,355, 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 | 103,543,355 | |
| -1 | -103,543,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,543,355.
Example:
1 x 103,543,355 = 103,543,355
and
-1 x -103,543,355 = 103,543,355
Notice both answers equal 103,543,355
With that explanation out of the way, let's continue. Next, we take the number 103,543,355 and divide it by 2:
103,543,355 ÷ 2 = 51,771,677.5
If the quotient is a whole number, then 2 and 51,771,677.5 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 | 103,543,355 | |
| -1 | -103,543,355 |
Now, we try dividing 103,543,355 by 3:
103,543,355 ÷ 3 = 34,514,451.6667
If the quotient is a whole number, then 3 and 34,514,451.6667 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 | 103,543,355 | |
| -1 | -103,543,355 |
Let's try dividing by 4:
103,543,355 ÷ 4 = 25,885,838.75
If the quotient is a whole number, then 4 and 25,885,838.75 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 | 103,543,355 | |
| -1 | 103,543,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 43 | 115 | 215 | 989 | 4,945 | 20,939 | 104,695 | 481,597 | 900,377 | 2,407,985 | 4,501,885 | 20,708,671 | 103,543,355 |
| -1 | -5 | -23 | -43 | -115 | -215 | -989 | -4,945 | -20,939 | -104,695 | -481,597 | -900,377 | -2,407,985 | -4,501,885 | -20,708,671 | -103,543,355 |
