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 2,173,687, 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 | 2,173,687 | |
-1 | -2,173,687 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,173,687.
Example:
1 x 2,173,687 = 2,173,687
and
-1 x -2,173,687 = 2,173,687
Notice both answers equal 2,173,687
With that explanation out of the way, let's continue. Next, we take the number 2,173,687 and divide it by 2:
2,173,687 ÷ 2 = 1,086,843.5
If the quotient is a whole number, then 2 and 1,086,843.5 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 | 2,173,687 | |
-1 | -2,173,687 |
Now, we try dividing 2,173,687 by 3:
2,173,687 ÷ 3 = 724,562.3333
If the quotient is a whole number, then 3 and 724,562.3333 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 | 2,173,687 | |
-1 | -2,173,687 |
Let's try dividing by 4:
2,173,687 ÷ 4 = 543,421.75
If the quotient is a whole number, then 4 and 543,421.75 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 | 2,173,687 | |
-1 | 2,173,687 |
If you did it right, you will end up with this table:
1 | 83 | 26,189 | 2,173,687 |
-1 | -83 | -26,189 | -2,173,687 |
