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 3,011,245, 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 | 3,011,245 | |
| -1 | -3,011,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,011,245.
Example:
1 x 3,011,245 = 3,011,245
and
-1 x -3,011,245 = 3,011,245
Notice both answers equal 3,011,245
With that explanation out of the way, let's continue. Next, we take the number 3,011,245 and divide it by 2:
3,011,245 ÷ 2 = 1,505,622.5
If the quotient is a whole number, then 2 and 1,505,622.5 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 | 3,011,245 | |
| -1 | -3,011,245 |
Now, we try dividing 3,011,245 by 3:
3,011,245 ÷ 3 = 1,003,748.3333
If the quotient is a whole number, then 3 and 1,003,748.3333 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 | 3,011,245 | |
| -1 | -3,011,245 |
Let's try dividing by 4:
3,011,245 ÷ 4 = 752,811.25
If the quotient is a whole number, then 4 and 752,811.25 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 | 3,011,245 | |
| -1 | 3,011,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 41 | 185 | 205 | 397 | 1,517 | 1,985 | 7,585 | 14,689 | 16,277 | 73,445 | 81,385 | 602,249 | 3,011,245 |
| -1 | -5 | -37 | -41 | -185 | -205 | -397 | -1,517 | -1,985 | -7,585 | -14,689 | -16,277 | -73,445 | -81,385 | -602,249 | -3,011,245 |
