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 524,014,045, 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 | 524,014,045 | |
| -1 | -524,014,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 524,014,045.
Example:
1 x 524,014,045 = 524,014,045
and
-1 x -524,014,045 = 524,014,045
Notice both answers equal 524,014,045
With that explanation out of the way, let's continue. Next, we take the number 524,014,045 and divide it by 2:
524,014,045 ÷ 2 = 262,007,022.5
If the quotient is a whole number, then 2 and 262,007,022.5 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 | 524,014,045 | |
| -1 | -524,014,045 |
Now, we try dividing 524,014,045 by 3:
524,014,045 ÷ 3 = 174,671,348.3333
If the quotient is a whole number, then 3 and 174,671,348.3333 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 | 524,014,045 | |
| -1 | -524,014,045 |
Let's try dividing by 4:
524,014,045 ÷ 4 = 131,003,511.25
If the quotient is a whole number, then 4 and 131,003,511.25 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 | 524,014,045 | |
| -1 | 524,014,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 103 | 235 | 515 | 4,841 | 21,649 | 24,205 | 108,245 | 1,017,503 | 2,229,847 | 5,087,515 | 11,149,235 | 104,802,809 | 524,014,045 |
| -1 | -5 | -47 | -103 | -235 | -515 | -4,841 | -21,649 | -24,205 | -108,245 | -1,017,503 | -2,229,847 | -5,087,515 | -11,149,235 | -104,802,809 | -524,014,045 |
