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 166,226,425, 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 | 166,226,425 | |
| -1 | -166,226,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,226,425.
Example:
1 x 166,226,425 = 166,226,425
and
-1 x -166,226,425 = 166,226,425
Notice both answers equal 166,226,425
With that explanation out of the way, let's continue. Next, we take the number 166,226,425 and divide it by 2:
166,226,425 ÷ 2 = 83,113,212.5
If the quotient is a whole number, then 2 and 83,113,212.5 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 | 166,226,425 | |
| -1 | -166,226,425 |
Now, we try dividing 166,226,425 by 3:
166,226,425 ÷ 3 = 55,408,808.3333
If the quotient is a whole number, then 3 and 55,408,808.3333 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 | 166,226,425 | |
| -1 | -166,226,425 |
Let's try dividing by 4:
166,226,425 ÷ 4 = 41,556,606.25
If the quotient is a whole number, then 4 and 41,556,606.25 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 | 166,226,425 | |
| -1 | 166,226,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 227 | 425 | 1,135 | 1,723 | 3,859 | 5,675 | 8,615 | 19,295 | 29,291 | 43,075 | 96,475 | 146,455 | 391,121 | 732,275 | 1,955,605 | 6,649,057 | 9,778,025 | 33,245,285 | 166,226,425 |
| -1 | -5 | -17 | -25 | -85 | -227 | -425 | -1,135 | -1,723 | -3,859 | -5,675 | -8,615 | -19,295 | -29,291 | -43,075 | -96,475 | -146,455 | -391,121 | -732,275 | -1,955,605 | -6,649,057 | -9,778,025 | -33,245,285 | -166,226,425 |
