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 63,030,245, 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 | 63,030,245 | |
| -1 | -63,030,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,030,245.
Example:
1 x 63,030,245 = 63,030,245
and
-1 x -63,030,245 = 63,030,245
Notice both answers equal 63,030,245
With that explanation out of the way, let's continue. Next, we take the number 63,030,245 and divide it by 2:
63,030,245 ÷ 2 = 31,515,122.5
If the quotient is a whole number, then 2 and 31,515,122.5 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 | 63,030,245 | |
| -1 | -63,030,245 |
Now, we try dividing 63,030,245 by 3:
63,030,245 ÷ 3 = 21,010,081.6667
If the quotient is a whole number, then 3 and 21,010,081.6667 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 | 63,030,245 | |
| -1 | -63,030,245 |
Let's try dividing by 4:
63,030,245 ÷ 4 = 15,757,561.25
If the quotient is a whole number, then 4 and 15,757,561.25 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 | 63,030,245 | |
| -1 | 63,030,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 139 | 445 | 695 | 1,019 | 5,095 | 12,371 | 61,855 | 90,691 | 141,641 | 453,455 | 708,205 | 12,606,049 | 63,030,245 |
| -1 | -5 | -89 | -139 | -445 | -695 | -1,019 | -5,095 | -12,371 | -61,855 | -90,691 | -141,641 | -453,455 | -708,205 | -12,606,049 | -63,030,245 |
