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 9,050,069, 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 | 9,050,069 | |
| -1 | -9,050,069 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,050,069.
Example:
1 x 9,050,069 = 9,050,069
and
-1 x -9,050,069 = 9,050,069
Notice both answers equal 9,050,069
With that explanation out of the way, let's continue. Next, we take the number 9,050,069 and divide it by 2:
9,050,069 ÷ 2 = 4,525,034.5
If the quotient is a whole number, then 2 and 4,525,034.5 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 | 9,050,069 | |
| -1 | -9,050,069 |
Now, we try dividing 9,050,069 by 3:
9,050,069 ÷ 3 = 3,016,689.6667
If the quotient is a whole number, then 3 and 3,016,689.6667 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 | 9,050,069 | |
| -1 | -9,050,069 |
Let's try dividing by 4:
9,050,069 ÷ 4 = 2,262,517.25
If the quotient is a whole number, then 4 and 2,262,517.25 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 | 9,050,069 | |
| -1 | 9,050,069 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 59 | 119 | 413 | 1,003 | 1,289 | 7,021 | 9,023 | 21,913 | 76,051 | 153,391 | 532,357 | 1,292,867 | 9,050,069 |
| -1 | -7 | -17 | -59 | -119 | -413 | -1,003 | -1,289 | -7,021 | -9,023 | -21,913 | -76,051 | -153,391 | -532,357 | -1,292,867 | -9,050,069 |
