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 66,777,445, 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 | 66,777,445 | |
| -1 | -66,777,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,777,445.
Example:
1 x 66,777,445 = 66,777,445
and
-1 x -66,777,445 = 66,777,445
Notice both answers equal 66,777,445
With that explanation out of the way, let's continue. Next, we take the number 66,777,445 and divide it by 2:
66,777,445 ÷ 2 = 33,388,722.5
If the quotient is a whole number, then 2 and 33,388,722.5 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 | 66,777,445 | |
| -1 | -66,777,445 |
Now, we try dividing 66,777,445 by 3:
66,777,445 ÷ 3 = 22,259,148.3333
If the quotient is a whole number, then 3 and 22,259,148.3333 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 | 66,777,445 | |
| -1 | -66,777,445 |
Let's try dividing by 4:
66,777,445 ÷ 4 = 16,694,361.25
If the quotient is a whole number, then 4 and 16,694,361.25 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 | 66,777,445 | |
| -1 | 66,777,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 49 | 85 | 119 | 245 | 595 | 833 | 4,165 | 16,033 | 80,165 | 112,231 | 272,561 | 561,155 | 785,617 | 1,362,805 | 1,907,927 | 3,928,085 | 9,539,635 | 13,355,489 | 66,777,445 |
| -1 | -5 | -7 | -17 | -35 | -49 | -85 | -119 | -245 | -595 | -833 | -4,165 | -16,033 | -80,165 | -112,231 | -272,561 | -561,155 | -785,617 | -1,362,805 | -1,907,927 | -3,928,085 | -9,539,635 | -13,355,489 | -66,777,445 |
