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 553,062,523, 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 | 553,062,523 | |
| -1 | -553,062,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 553,062,523.
Example:
1 x 553,062,523 = 553,062,523
and
-1 x -553,062,523 = 553,062,523
Notice both answers equal 553,062,523
With that explanation out of the way, let's continue. Next, we take the number 553,062,523 and divide it by 2:
553,062,523 ÷ 2 = 276,531,261.5
If the quotient is a whole number, then 2 and 276,531,261.5 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 | 553,062,523 | |
| -1 | -553,062,523 |
Now, we try dividing 553,062,523 by 3:
553,062,523 ÷ 3 = 184,354,174.3333
If the quotient is a whole number, then 3 and 184,354,174.3333 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 | 553,062,523 | |
| -1 | -553,062,523 |
Let's try dividing by 4:
553,062,523 ÷ 4 = 138,265,630.75
If the quotient is a whole number, then 4 and 138,265,630.75 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 | 553,062,523 | |
| -1 | 553,062,523 |
If you did it right, you will end up with this table:
| 1 | 13 | 71 | 223 | 923 | 2,687 | 2,899 | 15,833 | 34,931 | 190,777 | 205,829 | 599,201 | 2,480,101 | 7,789,613 | 42,543,271 | 553,062,523 |
| -1 | -13 | -71 | -223 | -923 | -2,687 | -2,899 | -15,833 | -34,931 | -190,777 | -205,829 | -599,201 | -2,480,101 | -7,789,613 | -42,543,271 | -553,062,523 |
