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 64,111,511, 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 | 64,111,511 | |
| -1 | -64,111,511 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,111,511.
Example:
1 x 64,111,511 = 64,111,511
and
-1 x -64,111,511 = 64,111,511
Notice both answers equal 64,111,511
With that explanation out of the way, let's continue. Next, we take the number 64,111,511 and divide it by 2:
64,111,511 ÷ 2 = 32,055,755.5
If the quotient is a whole number, then 2 and 32,055,755.5 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 | 64,111,511 | |
| -1 | -64,111,511 |
Now, we try dividing 64,111,511 by 3:
64,111,511 ÷ 3 = 21,370,503.6667
If the quotient is a whole number, then 3 and 21,370,503.6667 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 | 64,111,511 | |
| -1 | -64,111,511 |
Let's try dividing by 4:
64,111,511 ÷ 4 = 16,027,877.75
If the quotient is a whole number, then 4 and 16,027,877.75 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 | 64,111,511 | |
| -1 | 64,111,511 |
If you did it right, you will end up with this table:
| 1 | 23 | 107 | 109 | 239 | 2,461 | 2,507 | 5,497 | 11,663 | 25,573 | 26,051 | 268,249 | 588,179 | 599,173 | 2,787,457 | 64,111,511 |
| -1 | -23 | -107 | -109 | -239 | -2,461 | -2,507 | -5,497 | -11,663 | -25,573 | -26,051 | -268,249 | -588,179 | -599,173 | -2,787,457 | -64,111,511 |
