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 19,050,847, 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 | 19,050,847 | |
-1 | -19,050,847 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,050,847.
Example:
1 x 19,050,847 = 19,050,847
and
-1 x -19,050,847 = 19,050,847
Notice both answers equal 19,050,847
With that explanation out of the way, let's continue. Next, we take the number 19,050,847 and divide it by 2:
19,050,847 ÷ 2 = 9,525,423.5
If the quotient is a whole number, then 2 and 9,525,423.5 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 | 19,050,847 | |
-1 | -19,050,847 |
Now, we try dividing 19,050,847 by 3:
19,050,847 ÷ 3 = 6,350,282.3333
If the quotient is a whole number, then 3 and 6,350,282.3333 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 | 19,050,847 | |
-1 | -19,050,847 |
Let's try dividing by 4:
19,050,847 ÷ 4 = 4,762,711.75
If the quotient is a whole number, then 4 and 4,762,711.75 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 | 19,050,847 | |
-1 | 19,050,847 |
If you did it right, you will end up with this table:
1 | 67 | 284,341 | 19,050,847 |
-1 | -67 | -284,341 | -19,050,847 |
