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 2,111,071, 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 | 2,111,071 | |
-1 | -2,111,071 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,111,071.
Example:
1 x 2,111,071 = 2,111,071
and
-1 x -2,111,071 = 2,111,071
Notice both answers equal 2,111,071
With that explanation out of the way, let's continue. Next, we take the number 2,111,071 and divide it by 2:
2,111,071 ÷ 2 = 1,055,535.5
If the quotient is a whole number, then 2 and 1,055,535.5 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 | 2,111,071 | |
-1 | -2,111,071 |
Now, we try dividing 2,111,071 by 3:
2,111,071 ÷ 3 = 703,690.3333
If the quotient is a whole number, then 3 and 703,690.3333 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 | 2,111,071 | |
-1 | -2,111,071 |
Let's try dividing by 4:
2,111,071 ÷ 4 = 527,767.75
If the quotient is a whole number, then 4 and 527,767.75 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 | 2,111,071 | |
-1 | 2,111,071 |
If you did it right, you will end up with this table:
1 | 19 | 111,109 | 2,111,071 |
-1 | -19 | -111,109 | -2,111,071 |
