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 312,302,539, 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 | 312,302,539 | |
-1 | -312,302,539 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 312,302,539.
Example:
1 x 312,302,539 = 312,302,539
and
-1 x -312,302,539 = 312,302,539
Notice both answers equal 312,302,539
With that explanation out of the way, let's continue. Next, we take the number 312,302,539 and divide it by 2:
312,302,539 ÷ 2 = 156,151,269.5
If the quotient is a whole number, then 2 and 156,151,269.5 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 | 312,302,539 | |
-1 | -312,302,539 |
Now, we try dividing 312,302,539 by 3:
312,302,539 ÷ 3 = 104,100,846.3333
If the quotient is a whole number, then 3 and 104,100,846.3333 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 | 312,302,539 | |
-1 | -312,302,539 |
Let's try dividing by 4:
312,302,539 ÷ 4 = 78,075,634.75
If the quotient is a whole number, then 4 and 78,075,634.75 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 | 312,302,539 | |
-1 | 312,302,539 |
If you did it right, you will end up with this table:
1 | 547 | 570,937 | 312,302,539 |
-1 | -547 | -570,937 | -312,302,539 |
