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 63,016,135, 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 | 63,016,135 | |
| -1 | -63,016,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,016,135.
Example:
1 x 63,016,135 = 63,016,135
and
-1 x -63,016,135 = 63,016,135
Notice both answers equal 63,016,135
With that explanation out of the way, let's continue. Next, we take the number 63,016,135 and divide it by 2:
63,016,135 ÷ 2 = 31,508,067.5
If the quotient is a whole number, then 2 and 31,508,067.5 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 | 63,016,135 | |
| -1 | -63,016,135 |
Now, we try dividing 63,016,135 by 3:
63,016,135 ÷ 3 = 21,005,378.3333
If the quotient is a whole number, then 3 and 21,005,378.3333 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 | 63,016,135 | |
| -1 | -63,016,135 |
Let's try dividing by 4:
63,016,135 ÷ 4 = 15,754,033.75
If the quotient is a whole number, then 4 and 15,754,033.75 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 | 63,016,135 | |
| -1 | 63,016,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 138,497 | 692,485 | 969,479 | 1,800,461 | 4,847,395 | 9,002,305 | 12,603,227 | 63,016,135 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -138,497 | -692,485 | -969,479 | -1,800,461 | -4,847,395 | -9,002,305 | -12,603,227 | -63,016,135 |
