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 66,026,225, 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 | 66,026,225 | |
| -1 | -66,026,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,026,225.
Example:
1 x 66,026,225 = 66,026,225
and
-1 x -66,026,225 = 66,026,225
Notice both answers equal 66,026,225
With that explanation out of the way, let's continue. Next, we take the number 66,026,225 and divide it by 2:
66,026,225 ÷ 2 = 33,013,112.5
If the quotient is a whole number, then 2 and 33,013,112.5 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 | 66,026,225 | |
| -1 | -66,026,225 |
Now, we try dividing 66,026,225 by 3:
66,026,225 ÷ 3 = 22,008,741.6667
If the quotient is a whole number, then 3 and 22,008,741.6667 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 | 66,026,225 | |
| -1 | -66,026,225 |
Let's try dividing by 4:
66,026,225 ÷ 4 = 16,506,556.25
If the quotient is a whole number, then 4 and 16,506,556.25 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 | 66,026,225 | |
| -1 | 66,026,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 79 | 101 | 331 | 395 | 505 | 1,655 | 1,975 | 2,525 | 7,979 | 8,275 | 26,149 | 33,431 | 39,895 | 130,745 | 167,155 | 199,475 | 653,725 | 835,775 | 2,641,049 | 13,205,245 | 66,026,225 |
| -1 | -5 | -25 | -79 | -101 | -331 | -395 | -505 | -1,655 | -1,975 | -2,525 | -7,979 | -8,275 | -26,149 | -33,431 | -39,895 | -130,745 | -167,155 | -199,475 | -653,725 | -835,775 | -2,641,049 | -13,205,245 | -66,026,225 |
