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 66,526,537, 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 | 66,526,537 | |
| -1 | -66,526,537 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,526,537.
Example:
1 x 66,526,537 = 66,526,537
and
-1 x -66,526,537 = 66,526,537
Notice both answers equal 66,526,537
With that explanation out of the way, let's continue. Next, we take the number 66,526,537 and divide it by 2:
66,526,537 ÷ 2 = 33,263,268.5
If the quotient is a whole number, then 2 and 33,263,268.5 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 | 66,526,537 | |
| -1 | -66,526,537 |
Now, we try dividing 66,526,537 by 3:
66,526,537 ÷ 3 = 22,175,512.3333
If the quotient is a whole number, then 3 and 22,175,512.3333 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 | 66,526,537 | |
| -1 | -66,526,537 |
Let's try dividing by 4:
66,526,537 ÷ 4 = 16,631,634.25
If the quotient is a whole number, then 4 and 16,631,634.25 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 | 66,526,537 | |
| -1 | 66,526,537 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 127 | 889 | 1,397 | 6,803 | 9,779 | 47,621 | 74,833 | 523,831 | 863,981 | 6,047,867 | 9,503,791 | 66,526,537 |
| -1 | -7 | -11 | -77 | -127 | -889 | -1,397 | -6,803 | -9,779 | -47,621 | -74,833 | -523,831 | -863,981 | -6,047,867 | -9,503,791 | -66,526,537 |
