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 331,525,679, 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 | 331,525,679 | |
-1 | -331,525,679 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,525,679.
Example:
1 x 331,525,679 = 331,525,679
and
-1 x -331,525,679 = 331,525,679
Notice both answers equal 331,525,679
With that explanation out of the way, let's continue. Next, we take the number 331,525,679 and divide it by 2:
331,525,679 ÷ 2 = 165,762,839.5
If the quotient is a whole number, then 2 and 165,762,839.5 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 | 331,525,679 | |
-1 | -331,525,679 |
Now, we try dividing 331,525,679 by 3:
331,525,679 ÷ 3 = 110,508,559.6667
If the quotient is a whole number, then 3 and 110,508,559.6667 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 | 331,525,679 | |
-1 | -331,525,679 |
Let's try dividing by 4:
331,525,679 ÷ 4 = 82,881,419.75
If the quotient is a whole number, then 4 and 82,881,419.75 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 | 331,525,679 | |
-1 | 331,525,679 |
If you did it right, you will end up with this table:
1 | 3,361 | 98,639 | 331,525,679 |
-1 | -3,361 | -98,639 | -331,525,679 |
