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 8,166,575, 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 | 8,166,575 | |
-1 | -8,166,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,166,575.
Example:
1 x 8,166,575 = 8,166,575
and
-1 x -8,166,575 = 8,166,575
Notice both answers equal 8,166,575
With that explanation out of the way, let's continue. Next, we take the number 8,166,575 and divide it by 2:
8,166,575 ÷ 2 = 4,083,287.5
If the quotient is a whole number, then 2 and 4,083,287.5 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 | 8,166,575 | |
-1 | -8,166,575 |
Now, we try dividing 8,166,575 by 3:
8,166,575 ÷ 3 = 2,722,191.6667
If the quotient is a whole number, then 3 and 2,722,191.6667 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 | 8,166,575 | |
-1 | -8,166,575 |
Let's try dividing by 4:
8,166,575 ÷ 4 = 2,041,643.75
If the quotient is a whole number, then 4 and 2,041,643.75 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 | 8,166,575 | |
-1 | 8,166,575 |
If you did it right, you will end up with this table:
1 | 5 | 25 | 326,663 | 1,633,315 | 8,166,575 |
-1 | -5 | -25 | -326,663 | -1,633,315 | -8,166,575 |
