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 552,154,519, 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 | 552,154,519 | |
| -1 | -552,154,519 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 552,154,519.
Example:
1 x 552,154,519 = 552,154,519
and
-1 x -552,154,519 = 552,154,519
Notice both answers equal 552,154,519
With that explanation out of the way, let's continue. Next, we take the number 552,154,519 and divide it by 2:
552,154,519 ÷ 2 = 276,077,259.5
If the quotient is a whole number, then 2 and 276,077,259.5 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 | 552,154,519 | |
| -1 | -552,154,519 |
Now, we try dividing 552,154,519 by 3:
552,154,519 ÷ 3 = 184,051,506.3333
If the quotient is a whole number, then 3 and 184,051,506.3333 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 | 552,154,519 | |
| -1 | -552,154,519 |
Let's try dividing by 4:
552,154,519 ÷ 4 = 138,038,629.75
If the quotient is a whole number, then 4 and 138,038,629.75 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 | 552,154,519 | |
| -1 | 552,154,519 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 821 | 3,313 | 5,747 | 23,191 | 23,809 | 96,077 | 166,663 | 672,539 | 2,719,973 | 19,039,811 | 78,879,217 | 552,154,519 |
| -1 | -7 | -29 | -203 | -821 | -3,313 | -5,747 | -23,191 | -23,809 | -96,077 | -166,663 | -672,539 | -2,719,973 | -19,039,811 | -78,879,217 | -552,154,519 |
