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 552,450,131, 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 | 552,450,131 | |
-1 | -552,450,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 552,450,131.
Example:
1 x 552,450,131 = 552,450,131
and
-1 x -552,450,131 = 552,450,131
Notice both answers equal 552,450,131
With that explanation out of the way, let's continue. Next, we take the number 552,450,131 and divide it by 2:
552,450,131 ÷ 2 = 276,225,065.5
If the quotient is a whole number, then 2 and 276,225,065.5 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 | 552,450,131 | |
-1 | -552,450,131 |
Now, we try dividing 552,450,131 by 3:
552,450,131 ÷ 3 = 184,150,043.6667
If the quotient is a whole number, then 3 and 184,150,043.6667 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 | 552,450,131 | |
-1 | -552,450,131 |
Let's try dividing by 4:
552,450,131 ÷ 4 = 138,112,532.75
If the quotient is a whole number, then 4 and 138,112,532.75 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 | 552,450,131 | |
-1 | 552,450,131 |
If you did it right, you will end up with this table:
1 | 149 | 3,707,719 | 552,450,131 |
-1 | -149 | -3,707,719 | -552,450,131 |
