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 3,000,613, 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 | 3,000,613 | |
| -1 | -3,000,613 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,000,613.
Example:
1 x 3,000,613 = 3,000,613
and
-1 x -3,000,613 = 3,000,613
Notice both answers equal 3,000,613
With that explanation out of the way, let's continue. Next, we take the number 3,000,613 and divide it by 2:
3,000,613 ÷ 2 = 1,500,306.5
If the quotient is a whole number, then 2 and 1,500,306.5 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 | 3,000,613 | |
| -1 | -3,000,613 |
Now, we try dividing 3,000,613 by 3:
3,000,613 ÷ 3 = 1,000,204.3333
If the quotient is a whole number, then 3 and 1,000,204.3333 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 | 3,000,613 | |
| -1 | -3,000,613 |
Let's try dividing by 4:
3,000,613 ÷ 4 = 750,153.25
If the quotient is a whole number, then 4 and 750,153.25 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 | 3,000,613 | |
| -1 | 3,000,613 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 19 | 49 | 77 | 133 | 209 | 293 | 539 | 931 | 1,463 | 2,051 | 3,223 | 5,567 | 10,241 | 14,357 | 22,561 | 38,969 | 61,237 | 157,927 | 272,783 | 428,659 | 3,000,613 |
| -1 | -7 | -11 | -19 | -49 | -77 | -133 | -209 | -293 | -539 | -931 | -1,463 | -2,051 | -3,223 | -5,567 | -10,241 | -14,357 | -22,561 | -38,969 | -61,237 | -157,927 | -272,783 | -428,659 | -3,000,613 |
