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 9,090,347, 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 | 9,090,347 | |
| -1 | -9,090,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,090,347.
Example:
1 x 9,090,347 = 9,090,347
and
-1 x -9,090,347 = 9,090,347
Notice both answers equal 9,090,347
With that explanation out of the way, let's continue. Next, we take the number 9,090,347 and divide it by 2:
9,090,347 ÷ 2 = 4,545,173.5
If the quotient is a whole number, then 2 and 4,545,173.5 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 | 9,090,347 | |
| -1 | -9,090,347 |
Now, we try dividing 9,090,347 by 3:
9,090,347 ÷ 3 = 3,030,115.6667
If the quotient is a whole number, then 3 and 3,030,115.6667 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 | 9,090,347 | |
| -1 | -9,090,347 |
Let's try dividing by 4:
9,090,347 ÷ 4 = 2,272,586.75
If the quotient is a whole number, then 4 and 2,272,586.75 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 | 9,090,347 | |
| -1 | 9,090,347 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 163 | 217 | 257 | 1,141 | 1,799 | 5,053 | 7,967 | 35,371 | 41,891 | 55,769 | 293,237 | 1,298,621 | 9,090,347 |
| -1 | -7 | -31 | -163 | -217 | -257 | -1,141 | -1,799 | -5,053 | -7,967 | -35,371 | -41,891 | -55,769 | -293,237 | -1,298,621 | -9,090,347 |
