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 210,524,045, 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 | 210,524,045 | |
| -1 | -210,524,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 210,524,045.
Example:
1 x 210,524,045 = 210,524,045
and
-1 x -210,524,045 = 210,524,045
Notice both answers equal 210,524,045
With that explanation out of the way, let's continue. Next, we take the number 210,524,045 and divide it by 2:
210,524,045 ÷ 2 = 105,262,022.5
If the quotient is a whole number, then 2 and 105,262,022.5 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 | 210,524,045 | |
| -1 | -210,524,045 |
Now, we try dividing 210,524,045 by 3:
210,524,045 ÷ 3 = 70,174,681.6667
If the quotient is a whole number, then 3 and 70,174,681.6667 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 | 210,524,045 | |
| -1 | -210,524,045 |
Let's try dividing by 4:
210,524,045 ÷ 4 = 52,631,011.25
If the quotient is a whole number, then 4 and 52,631,011.25 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 | 210,524,045 | |
| -1 | 210,524,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 235 | 367 | 1,835 | 2,441 | 12,205 | 17,249 | 86,245 | 114,727 | 573,635 | 895,847 | 4,479,235 | 42,104,809 | 210,524,045 |
| -1 | -5 | -47 | -235 | -367 | -1,835 | -2,441 | -12,205 | -17,249 | -86,245 | -114,727 | -573,635 | -895,847 | -4,479,235 | -42,104,809 | -210,524,045 |
