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 8,909,951, 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 | 8,909,951 | |
-1 | -8,909,951 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,909,951.
Example:
1 x 8,909,951 = 8,909,951
and
-1 x -8,909,951 = 8,909,951
Notice both answers equal 8,909,951
With that explanation out of the way, let's continue. Next, we take the number 8,909,951 and divide it by 2:
8,909,951 ÷ 2 = 4,454,975.5
If the quotient is a whole number, then 2 and 4,454,975.5 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 | 8,909,951 | |
-1 | -8,909,951 |
Now, we try dividing 8,909,951 by 3:
8,909,951 ÷ 3 = 2,969,983.6667
If the quotient is a whole number, then 3 and 2,969,983.6667 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 | 8,909,951 | |
-1 | -8,909,951 |
Let's try dividing by 4:
8,909,951 ÷ 4 = 2,227,487.75
If the quotient is a whole number, then 4 and 2,227,487.75 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 | 8,909,951 | |
-1 | 8,909,951 |
If you did it right, you will end up with this table:
1 | 167 | 53,353 | 8,909,951 |
-1 | -167 | -53,353 | -8,909,951 |
