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 64,063,015, 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 | 64,063,015 | |
| -1 | -64,063,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,063,015.
Example:
1 x 64,063,015 = 64,063,015
and
-1 x -64,063,015 = 64,063,015
Notice both answers equal 64,063,015
With that explanation out of the way, let's continue. Next, we take the number 64,063,015 and divide it by 2:
64,063,015 ÷ 2 = 32,031,507.5
If the quotient is a whole number, then 2 and 32,031,507.5 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 | 64,063,015 | |
| -1 | -64,063,015 |
Now, we try dividing 64,063,015 by 3:
64,063,015 ÷ 3 = 21,354,338.3333
If the quotient is a whole number, then 3 and 21,354,338.3333 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 | 64,063,015 | |
| -1 | -64,063,015 |
Let's try dividing by 4:
64,063,015 ÷ 4 = 16,015,753.75
If the quotient is a whole number, then 4 and 16,015,753.75 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 | 64,063,015 | |
| -1 | 64,063,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 139 | 695 | 92,177 | 460,885 | 12,812,603 | 64,063,015 |
| -1 | -5 | -139 | -695 | -92,177 | -460,885 | -12,812,603 | -64,063,015 |
