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 63,105,665, 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 | 63,105,665 | |
| -1 | -63,105,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,105,665.
Example:
1 x 63,105,665 = 63,105,665
and
-1 x -63,105,665 = 63,105,665
Notice both answers equal 63,105,665
With that explanation out of the way, let's continue. Next, we take the number 63,105,665 and divide it by 2:
63,105,665 ÷ 2 = 31,552,832.5
If the quotient is a whole number, then 2 and 31,552,832.5 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 | 63,105,665 | |
| -1 | -63,105,665 |
Now, we try dividing 63,105,665 by 3:
63,105,665 ÷ 3 = 21,035,221.6667
If the quotient is a whole number, then 3 and 21,035,221.6667 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 | 63,105,665 | |
| -1 | -63,105,665 |
Let's try dividing by 4:
63,105,665 ÷ 4 = 15,776,416.25
If the quotient is a whole number, then 4 and 15,776,416.25 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 | 63,105,665 | |
| -1 | 63,105,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 127 | 635 | 889 | 4,445 | 14,197 | 70,985 | 99,379 | 496,895 | 1,803,019 | 9,015,095 | 12,621,133 | 63,105,665 |
| -1 | -5 | -7 | -35 | -127 | -635 | -889 | -4,445 | -14,197 | -70,985 | -99,379 | -496,895 | -1,803,019 | -9,015,095 | -12,621,133 | -63,105,665 |
