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 4,089,241, 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 | 4,089,241 | |
| -1 | -4,089,241 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,089,241.
Example:
1 x 4,089,241 = 4,089,241
and
-1 x -4,089,241 = 4,089,241
Notice both answers equal 4,089,241
With that explanation out of the way, let's continue. Next, we take the number 4,089,241 and divide it by 2:
4,089,241 ÷ 2 = 2,044,620.5
If the quotient is a whole number, then 2 and 2,044,620.5 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 | 4,089,241 | |
| -1 | -4,089,241 |
Now, we try dividing 4,089,241 by 3:
4,089,241 ÷ 3 = 1,363,080.3333
If the quotient is a whole number, then 3 and 1,363,080.3333 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 | 4,089,241 | |
| -1 | -4,089,241 |
Let's try dividing by 4:
4,089,241 ÷ 4 = 1,022,310.25
If the quotient is a whole number, then 4 and 1,022,310.25 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 | 4,089,241 | |
| -1 | 4,089,241 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 73 | 139 | 403 | 949 | 1,807 | 2,263 | 4,309 | 10,147 | 29,419 | 56,017 | 131,911 | 314,557 | 4,089,241 |
| -1 | -13 | -31 | -73 | -139 | -403 | -949 | -1,807 | -2,263 | -4,309 | -10,147 | -29,419 | -56,017 | -131,911 | -314,557 | -4,089,241 |
