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 245,541,523, 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 | 245,541,523 | |
| -1 | -245,541,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 245,541,523.
Example:
1 x 245,541,523 = 245,541,523
and
-1 x -245,541,523 = 245,541,523
Notice both answers equal 245,541,523
With that explanation out of the way, let's continue. Next, we take the number 245,541,523 and divide it by 2:
245,541,523 ÷ 2 = 122,770,761.5
If the quotient is a whole number, then 2 and 122,770,761.5 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 | 245,541,523 | |
| -1 | -245,541,523 |
Now, we try dividing 245,541,523 by 3:
245,541,523 ÷ 3 = 81,847,174.3333
If the quotient is a whole number, then 3 and 81,847,174.3333 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 | 245,541,523 | |
| -1 | -245,541,523 |
Let's try dividing by 4:
245,541,523 ÷ 4 = 61,385,380.75
If the quotient is a whole number, then 4 and 61,385,380.75 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 | 245,541,523 | |
| -1 | 245,541,523 |
If you did it right, you will end up with this table:
| 1 | 17 | 181 | 199 | 401 | 3,077 | 3,383 | 6,817 | 36,019 | 72,581 | 79,799 | 612,323 | 1,233,877 | 1,356,583 | 14,443,619 | 245,541,523 |
| -1 | -17 | -181 | -199 | -401 | -3,077 | -3,383 | -6,817 | -36,019 | -72,581 | -79,799 | -612,323 | -1,233,877 | -1,356,583 | -14,443,619 | -245,541,523 |
