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 320,524,153, 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 | 320,524,153 | |
-1 | -320,524,153 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 320,524,153.
Example:
1 x 320,524,153 = 320,524,153
and
-1 x -320,524,153 = 320,524,153
Notice both answers equal 320,524,153
With that explanation out of the way, let's continue. Next, we take the number 320,524,153 and divide it by 2:
320,524,153 ÷ 2 = 160,262,076.5
If the quotient is a whole number, then 2 and 160,262,076.5 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 | 320,524,153 | |
-1 | -320,524,153 |
Now, we try dividing 320,524,153 by 3:
320,524,153 ÷ 3 = 106,841,384.3333
If the quotient is a whole number, then 3 and 106,841,384.3333 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 | 320,524,153 | |
-1 | -320,524,153 |
Let's try dividing by 4:
320,524,153 ÷ 4 = 80,131,038.25
If the quotient is a whole number, then 4 and 80,131,038.25 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 | 320,524,153 | |
-1 | 320,524,153 |
If you did it right, you will end up with this table:
1 | 29 | 11,052,557 | 320,524,153 |
-1 | -29 | -11,052,557 | -320,524,153 |
