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 100,018,949, 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 | 100,018,949 | |
-1 | -100,018,949 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,018,949.
Example:
1 x 100,018,949 = 100,018,949
and
-1 x -100,018,949 = 100,018,949
Notice both answers equal 100,018,949
With that explanation out of the way, let's continue. Next, we take the number 100,018,949 and divide it by 2:
100,018,949 ÷ 2 = 50,009,474.5
If the quotient is a whole number, then 2 and 50,009,474.5 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 | 100,018,949 | |
-1 | -100,018,949 |
Now, we try dividing 100,018,949 by 3:
100,018,949 ÷ 3 = 33,339,649.6667
If the quotient is a whole number, then 3 and 33,339,649.6667 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 | 100,018,949 | |
-1 | -100,018,949 |
Let's try dividing by 4:
100,018,949 ÷ 4 = 25,004,737.25
If the quotient is a whole number, then 4 and 25,004,737.25 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 | 100,018,949 | |
-1 | 100,018,949 |
If you did it right, you will end up with this table:
1 | 9,209 | 10,861 | 100,018,949 |
-1 | -9,209 | -10,861 | -100,018,949 |
