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 64,414,133, 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 | 64,414,133 | |
| -1 | -64,414,133 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,414,133.
Example:
1 x 64,414,133 = 64,414,133
and
-1 x -64,414,133 = 64,414,133
Notice both answers equal 64,414,133
With that explanation out of the way, let's continue. Next, we take the number 64,414,133 and divide it by 2:
64,414,133 ÷ 2 = 32,207,066.5
If the quotient is a whole number, then 2 and 32,207,066.5 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 | 64,414,133 | |
| -1 | -64,414,133 |
Now, we try dividing 64,414,133 by 3:
64,414,133 ÷ 3 = 21,471,377.6667
If the quotient is a whole number, then 3 and 21,471,377.6667 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 | 64,414,133 | |
| -1 | -64,414,133 |
Let's try dividing by 4:
64,414,133 ÷ 4 = 16,103,533.25
If the quotient is a whole number, then 4 and 16,103,533.25 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 | 64,414,133 | |
| -1 | 64,414,133 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 53 | 203 | 371 | 1,537 | 5,987 | 10,759 | 41,909 | 173,623 | 317,311 | 1,215,361 | 2,221,177 | 9,202,019 | 64,414,133 |
| -1 | -7 | -29 | -53 | -203 | -371 | -1,537 | -5,987 | -10,759 | -41,909 | -173,623 | -317,311 | -1,215,361 | -2,221,177 | -9,202,019 | -64,414,133 |
