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 64,111,441, 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 | 64,111,441 | |
| -1 | -64,111,441 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,111,441.
Example:
1 x 64,111,441 = 64,111,441
and
-1 x -64,111,441 = 64,111,441
Notice both answers equal 64,111,441
With that explanation out of the way, let's continue. Next, we take the number 64,111,441 and divide it by 2:
64,111,441 ÷ 2 = 32,055,720.5
If the quotient is a whole number, then 2 and 32,055,720.5 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 | 64,111,441 | |
| -1 | -64,111,441 |
Now, we try dividing 64,111,441 by 3:
64,111,441 ÷ 3 = 21,370,480.3333
If the quotient is a whole number, then 3 and 21,370,480.3333 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 | 64,111,441 | |
| -1 | -64,111,441 |
Let's try dividing by 4:
64,111,441 ÷ 4 = 16,027,860.25
If the quotient is a whole number, then 4 and 16,027,860.25 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 | 64,111,441 | |
| -1 | 64,111,441 |
If you did it right, you will end up with this table:
| 1 | 31 | 83 | 2,573 | 24,917 | 772,427 | 2,068,111 | 64,111,441 |
| -1 | -31 | -83 | -2,573 | -24,917 | -772,427 | -2,068,111 | -64,111,441 |
