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 9,500,645, 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 | 9,500,645 | |
| -1 | -9,500,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,500,645.
Example:
1 x 9,500,645 = 9,500,645
and
-1 x -9,500,645 = 9,500,645
Notice both answers equal 9,500,645
With that explanation out of the way, let's continue. Next, we take the number 9,500,645 and divide it by 2:
9,500,645 ÷ 2 = 4,750,322.5
If the quotient is a whole number, then 2 and 4,750,322.5 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 | 9,500,645 | |
| -1 | -9,500,645 |
Now, we try dividing 9,500,645 by 3:
9,500,645 ÷ 3 = 3,166,881.6667
If the quotient is a whole number, then 3 and 3,166,881.6667 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 | 9,500,645 | |
| -1 | -9,500,645 |
Let's try dividing by 4:
9,500,645 ÷ 4 = 2,375,161.25
If the quotient is a whole number, then 4 and 2,375,161.25 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 | 9,500,645 | |
| -1 | 9,500,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 24,677 | 123,385 | 172,739 | 271,447 | 863,695 | 1,357,235 | 1,900,129 | 9,500,645 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -24,677 | -123,385 | -172,739 | -271,447 | -863,695 | -1,357,235 | -1,900,129 | -9,500,645 |
