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 526,245,149, 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 | 526,245,149 | |
| -1 | -526,245,149 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 526,245,149.
Example:
1 x 526,245,149 = 526,245,149
and
-1 x -526,245,149 = 526,245,149
Notice both answers equal 526,245,149
With that explanation out of the way, let's continue. Next, we take the number 526,245,149 and divide it by 2:
526,245,149 ÷ 2 = 263,122,574.5
If the quotient is a whole number, then 2 and 263,122,574.5 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 | 526,245,149 | |
| -1 | -526,245,149 |
Now, we try dividing 526,245,149 by 3:
526,245,149 ÷ 3 = 175,415,049.6667
If the quotient is a whole number, then 3 and 175,415,049.6667 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 | 526,245,149 | |
| -1 | -526,245,149 |
Let's try dividing by 4:
526,245,149 ÷ 4 = 131,561,287.25
If the quotient is a whole number, then 4 and 131,561,287.25 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 | 526,245,149 | |
| -1 | 526,245,149 |
If you did it right, you will end up with this table:
| 1 | 17 | 79 | 83 | 1,343 | 1,411 | 4,721 | 6,557 | 80,257 | 111,469 | 372,959 | 391,843 | 6,340,303 | 6,661,331 | 30,955,597 | 526,245,149 |
| -1 | -17 | -79 | -83 | -1,343 | -1,411 | -4,721 | -6,557 | -80,257 | -111,469 | -372,959 | -391,843 | -6,340,303 | -6,661,331 | -30,955,597 | -526,245,149 |
