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 123,442,897, 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 | 123,442,897 | |
-1 | -123,442,897 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,442,897.
Example:
1 x 123,442,897 = 123,442,897
and
-1 x -123,442,897 = 123,442,897
Notice both answers equal 123,442,897
With that explanation out of the way, let's continue. Next, we take the number 123,442,897 and divide it by 2:
123,442,897 ÷ 2 = 61,721,448.5
If the quotient is a whole number, then 2 and 61,721,448.5 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 | 123,442,897 | |
-1 | -123,442,897 |
Now, we try dividing 123,442,897 by 3:
123,442,897 ÷ 3 = 41,147,632.3333
If the quotient is a whole number, then 3 and 41,147,632.3333 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 | 123,442,897 | |
-1 | -123,442,897 |
Let's try dividing by 4:
123,442,897 ÷ 4 = 30,860,724.25
If the quotient is a whole number, then 4 and 30,860,724.25 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 | 123,442,897 | |
-1 | 123,442,897 |
If you did it right, you will end up with this table:
1 | 557 | 221,621 | 123,442,897 |
-1 | -557 | -221,621 | -123,442,897 |
