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 63,403,115, 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 | 63,403,115 | |
| -1 | -63,403,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,403,115.
Example:
1 x 63,403,115 = 63,403,115
and
-1 x -63,403,115 = 63,403,115
Notice both answers equal 63,403,115
With that explanation out of the way, let's continue. Next, we take the number 63,403,115 and divide it by 2:
63,403,115 ÷ 2 = 31,701,557.5
If the quotient is a whole number, then 2 and 31,701,557.5 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 | 63,403,115 | |
| -1 | -63,403,115 |
Now, we try dividing 63,403,115 by 3:
63,403,115 ÷ 3 = 21,134,371.6667
If the quotient is a whole number, then 3 and 21,134,371.6667 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 | 63,403,115 | |
| -1 | -63,403,115 |
Let's try dividing by 4:
63,403,115 ÷ 4 = 15,850,778.75
If the quotient is a whole number, then 4 and 15,850,778.75 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 | 63,403,115 | |
| -1 | 63,403,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 239 | 1,195 | 3,121 | 4,063 | 15,605 | 20,315 | 53,057 | 265,285 | 745,919 | 3,729,595 | 12,680,623 | 63,403,115 |
| -1 | -5 | -17 | -85 | -239 | -1,195 | -3,121 | -4,063 | -15,605 | -20,315 | -53,057 | -265,285 | -745,919 | -3,729,595 | -12,680,623 | -63,403,115 |
