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 8,423,705, 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 | 8,423,705 | |
-1 | -8,423,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,423,705.
Example:
1 x 8,423,705 = 8,423,705
and
-1 x -8,423,705 = 8,423,705
Notice both answers equal 8,423,705
With that explanation out of the way, let's continue. Next, we take the number 8,423,705 and divide it by 2:
8,423,705 ÷ 2 = 4,211,852.5
If the quotient is a whole number, then 2 and 4,211,852.5 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 | 8,423,705 | |
-1 | -8,423,705 |
Now, we try dividing 8,423,705 by 3:
8,423,705 ÷ 3 = 2,807,901.6667
If the quotient is a whole number, then 3 and 2,807,901.6667 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 | 8,423,705 | |
-1 | -8,423,705 |
Let's try dividing by 4:
8,423,705 ÷ 4 = 2,105,926.25
If the quotient is a whole number, then 4 and 2,105,926.25 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 | 8,423,705 | |
-1 | 8,423,705 |
If you did it right, you will end up with this table:
1 | 5 | 1,684,741 | 8,423,705 |
-1 | -5 | -1,684,741 | -8,423,705 |
