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 39,265,471, 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 | 39,265,471 | |
-1 | -39,265,471 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 39,265,471.
Example:
1 x 39,265,471 = 39,265,471
and
-1 x -39,265,471 = 39,265,471
Notice both answers equal 39,265,471
With that explanation out of the way, let's continue. Next, we take the number 39,265,471 and divide it by 2:
39,265,471 ÷ 2 = 19,632,735.5
If the quotient is a whole number, then 2 and 19,632,735.5 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 | 39,265,471 | |
-1 | -39,265,471 |
Now, we try dividing 39,265,471 by 3:
39,265,471 ÷ 3 = 13,088,490.3333
If the quotient is a whole number, then 3 and 13,088,490.3333 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 | 39,265,471 | |
-1 | -39,265,471 |
Let's try dividing by 4:
39,265,471 ÷ 4 = 9,816,367.75
If the quotient is a whole number, then 4 and 9,816,367.75 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 | 39,265,471 | |
-1 | 39,265,471 |
If you did it right, you will end up with this table:
1 | 7 | 5,609,353 | 39,265,471 |
-1 | -7 | -5,609,353 | -39,265,471 |
