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 64,656,427, 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 | 64,656,427 | |
| -1 | -64,656,427 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,656,427.
Example:
1 x 64,656,427 = 64,656,427
and
-1 x -64,656,427 = 64,656,427
Notice both answers equal 64,656,427
With that explanation out of the way, let's continue. Next, we take the number 64,656,427 and divide it by 2:
64,656,427 ÷ 2 = 32,328,213.5
If the quotient is a whole number, then 2 and 32,328,213.5 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 | 64,656,427 | |
| -1 | -64,656,427 |
Now, we try dividing 64,656,427 by 3:
64,656,427 ÷ 3 = 21,552,142.3333
If the quotient is a whole number, then 3 and 21,552,142.3333 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 | 64,656,427 | |
| -1 | -64,656,427 |
Let's try dividing by 4:
64,656,427 ÷ 4 = 16,164,106.75
If the quotient is a whole number, then 4 and 16,164,106.75 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 | 64,656,427 | |
| -1 | 64,656,427 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 37 | 253 | 407 | 851 | 6,907 | 9,361 | 75,977 | 158,861 | 255,559 | 1,747,471 | 2,811,149 | 5,877,857 | 64,656,427 |
| -1 | -11 | -23 | -37 | -253 | -407 | -851 | -6,907 | -9,361 | -75,977 | -158,861 | -255,559 | -1,747,471 | -2,811,149 | -5,877,857 | -64,656,427 |
