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 63,580,135, 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 | 63,580,135 | |
| -1 | -63,580,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,580,135.
Example:
1 x 63,580,135 = 63,580,135
and
-1 x -63,580,135 = 63,580,135
Notice both answers equal 63,580,135
With that explanation out of the way, let's continue. Next, we take the number 63,580,135 and divide it by 2:
63,580,135 ÷ 2 = 31,790,067.5
If the quotient is a whole number, then 2 and 31,790,067.5 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 | 63,580,135 | |
| -1 | -63,580,135 |
Now, we try dividing 63,580,135 by 3:
63,580,135 ÷ 3 = 21,193,378.3333
If the quotient is a whole number, then 3 and 21,193,378.3333 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 | 63,580,135 | |
| -1 | -63,580,135 |
Let's try dividing by 4:
63,580,135 ÷ 4 = 15,895,033.75
If the quotient is a whole number, then 4 and 15,895,033.75 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 | 63,580,135 | |
| -1 | 63,580,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 205 | 331 | 937 | 1,655 | 4,685 | 13,571 | 38,417 | 67,855 | 192,085 | 310,147 | 1,550,735 | 12,716,027 | 63,580,135 |
| -1 | -5 | -41 | -205 | -331 | -937 | -1,655 | -4,685 | -13,571 | -38,417 | -67,855 | -192,085 | -310,147 | -1,550,735 | -12,716,027 | -63,580,135 |
