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 552,043,781, 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 | 552,043,781 | |
-1 | -552,043,781 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 552,043,781.
Example:
1 x 552,043,781 = 552,043,781
and
-1 x -552,043,781 = 552,043,781
Notice both answers equal 552,043,781
With that explanation out of the way, let's continue. Next, we take the number 552,043,781 and divide it by 2:
552,043,781 ÷ 2 = 276,021,890.5
If the quotient is a whole number, then 2 and 276,021,890.5 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 | 552,043,781 | |
-1 | -552,043,781 |
Now, we try dividing 552,043,781 by 3:
552,043,781 ÷ 3 = 184,014,593.6667
If the quotient is a whole number, then 3 and 184,014,593.6667 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 | 552,043,781 | |
-1 | -552,043,781 |
Let's try dividing by 4:
552,043,781 ÷ 4 = 138,010,945.25
If the quotient is a whole number, then 4 and 138,010,945.25 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 | 552,043,781 | |
-1 | 552,043,781 |
If you did it right, you will end up with this table:
1 | 97 | 5,691,173 | 552,043,781 |
-1 | -97 | -5,691,173 | -552,043,781 |
