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 19,561,793, 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 | 19,561,793 | |
-1 | -19,561,793 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,561,793.
Example:
1 x 19,561,793 = 19,561,793
and
-1 x -19,561,793 = 19,561,793
Notice both answers equal 19,561,793
With that explanation out of the way, let's continue. Next, we take the number 19,561,793 and divide it by 2:
19,561,793 ÷ 2 = 9,780,896.5
If the quotient is a whole number, then 2 and 9,780,896.5 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 | 19,561,793 | |
-1 | -19,561,793 |
Now, we try dividing 19,561,793 by 3:
19,561,793 ÷ 3 = 6,520,597.6667
If the quotient is a whole number, then 3 and 6,520,597.6667 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 | 19,561,793 | |
-1 | -19,561,793 |
Let's try dividing by 4:
19,561,793 ÷ 4 = 4,890,448.25
If the quotient is a whole number, then 4 and 4,890,448.25 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 | 19,561,793 | |
-1 | 19,561,793 |
If you did it right, you will end up with this table:
1 | 163 | 120,011 | 19,561,793 |
-1 | -163 | -120,011 | -19,561,793 |
