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 4,011,245, 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 | 4,011,245 | |
| -1 | -4,011,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,011,245.
Example:
1 x 4,011,245 = 4,011,245
and
-1 x -4,011,245 = 4,011,245
Notice both answers equal 4,011,245
With that explanation out of the way, let's continue. Next, we take the number 4,011,245 and divide it by 2:
4,011,245 ÷ 2 = 2,005,622.5
If the quotient is a whole number, then 2 and 2,005,622.5 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 | 4,011,245 | |
| -1 | -4,011,245 |
Now, we try dividing 4,011,245 by 3:
4,011,245 ÷ 3 = 1,337,081.6667
If the quotient is a whole number, then 3 and 1,337,081.6667 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 | 4,011,245 | |
| -1 | -4,011,245 |
Let's try dividing by 4:
4,011,245 ÷ 4 = 1,002,811.25
If the quotient is a whole number, then 4 and 1,002,811.25 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 | 4,011,245 | |
| -1 | 4,011,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 1,085 | 3,697 | 18,485 | 25,879 | 114,607 | 129,395 | 573,035 | 802,249 | 4,011,245 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -1,085 | -3,697 | -18,485 | -25,879 | -114,607 | -129,395 | -573,035 | -802,249 | -4,011,245 |
