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 39,351,973, 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 | 39,351,973 | |
-1 | -39,351,973 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 39,351,973.
Example:
1 x 39,351,973 = 39,351,973
and
-1 x -39,351,973 = 39,351,973
Notice both answers equal 39,351,973
With that explanation out of the way, let's continue. Next, we take the number 39,351,973 and divide it by 2:
39,351,973 ÷ 2 = 19,675,986.5
If the quotient is a whole number, then 2 and 19,675,986.5 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 | 39,351,973 | |
-1 | -39,351,973 |
Now, we try dividing 39,351,973 by 3:
39,351,973 ÷ 3 = 13,117,324.3333
If the quotient is a whole number, then 3 and 13,117,324.3333 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 | 39,351,973 | |
-1 | -39,351,973 |
Let's try dividing by 4:
39,351,973 ÷ 4 = 9,837,993.25
If the quotient is a whole number, then 4 and 9,837,993.25 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 | 39,351,973 | |
-1 | 39,351,973 |
If you did it right, you will end up with this table:
1 | 89 | 442,157 | 39,351,973 |
-1 | -89 | -442,157 | -39,351,973 |
