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 103,511,345, 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 | 103,511,345 | |
| -1 | -103,511,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,511,345.
Example:
1 x 103,511,345 = 103,511,345
and
-1 x -103,511,345 = 103,511,345
Notice both answers equal 103,511,345
With that explanation out of the way, let's continue. Next, we take the number 103,511,345 and divide it by 2:
103,511,345 ÷ 2 = 51,755,672.5
If the quotient is a whole number, then 2 and 51,755,672.5 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 | 103,511,345 | |
| -1 | -103,511,345 |
Now, we try dividing 103,511,345 by 3:
103,511,345 ÷ 3 = 34,503,781.6667
If the quotient is a whole number, then 3 and 34,503,781.6667 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 | 103,511,345 | |
| -1 | -103,511,345 |
Let's try dividing by 4:
103,511,345 ÷ 4 = 25,877,836.25
If the quotient is a whole number, then 4 and 25,877,836.25 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 | 103,511,345 | |
| -1 | 103,511,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,579 | 1,873 | 7,895 | 9,365 | 11,053 | 13,111 | 55,265 | 65,555 | 2,957,467 | 14,787,335 | 20,702,269 | 103,511,345 |
| -1 | -5 | -7 | -35 | -1,579 | -1,873 | -7,895 | -9,365 | -11,053 | -13,111 | -55,265 | -65,555 | -2,957,467 | -14,787,335 | -20,702,269 | -103,511,345 |
