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 105,304,535, 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 | 105,304,535 | |
| -1 | -105,304,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 105,304,535.
Example:
1 x 105,304,535 = 105,304,535
and
-1 x -105,304,535 = 105,304,535
Notice both answers equal 105,304,535
With that explanation out of the way, let's continue. Next, we take the number 105,304,535 and divide it by 2:
105,304,535 ÷ 2 = 52,652,267.5
If the quotient is a whole number, then 2 and 52,652,267.5 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 | 105,304,535 | |
| -1 | -105,304,535 |
Now, we try dividing 105,304,535 by 3:
105,304,535 ÷ 3 = 35,101,511.6667
If the quotient is a whole number, then 3 and 35,101,511.6667 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 | 105,304,535 | |
| -1 | -105,304,535 |
Let's try dividing by 4:
105,304,535 ÷ 4 = 26,326,133.75
If the quotient is a whole number, then 4 and 26,326,133.75 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 | 105,304,535 | |
| -1 | 105,304,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 787 | 3,823 | 3,935 | 5,509 | 19,115 | 26,761 | 27,545 | 133,805 | 3,008,701 | 15,043,505 | 21,060,907 | 105,304,535 |
| -1 | -5 | -7 | -35 | -787 | -3,823 | -3,935 | -5,509 | -19,115 | -26,761 | -27,545 | -133,805 | -3,008,701 | -15,043,505 | -21,060,907 | -105,304,535 |
