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 8,745,281, 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 | 8,745,281 | |
-1 | -8,745,281 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,745,281.
Example:
1 x 8,745,281 = 8,745,281
and
-1 x -8,745,281 = 8,745,281
Notice both answers equal 8,745,281
With that explanation out of the way, let's continue. Next, we take the number 8,745,281 and divide it by 2:
8,745,281 ÷ 2 = 4,372,640.5
If the quotient is a whole number, then 2 and 4,372,640.5 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 | 8,745,281 | |
-1 | -8,745,281 |
Now, we try dividing 8,745,281 by 3:
8,745,281 ÷ 3 = 2,915,093.6667
If the quotient is a whole number, then 3 and 2,915,093.6667 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 | 8,745,281 | |
-1 | -8,745,281 |
Let's try dividing by 4:
8,745,281 ÷ 4 = 2,186,320.25
If the quotient is a whole number, then 4 and 2,186,320.25 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 | 8,745,281 | |
-1 | 8,745,281 |
If you did it right, you will end up with this table:
1 | 229 | 38,189 | 8,745,281 |
-1 | -229 | -38,189 | -8,745,281 |
