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 166,226,423, 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 | 166,226,423 | |
| -1 | -166,226,423 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,226,423.
Example:
1 x 166,226,423 = 166,226,423
and
-1 x -166,226,423 = 166,226,423
Notice both answers equal 166,226,423
With that explanation out of the way, let's continue. Next, we take the number 166,226,423 and divide it by 2:
166,226,423 ÷ 2 = 83,113,211.5
If the quotient is a whole number, then 2 and 83,113,211.5 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 | 166,226,423 | |
| -1 | -166,226,423 |
Now, we try dividing 166,226,423 by 3:
166,226,423 ÷ 3 = 55,408,807.6667
If the quotient is a whole number, then 3 and 55,408,807.6667 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 | 166,226,423 | |
| -1 | -166,226,423 |
Let's try dividing by 4:
166,226,423 ÷ 4 = 41,556,605.75
If the quotient is a whole number, then 4 and 41,556,605.75 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 | 166,226,423 | |
| -1 | 166,226,423 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 59 | 451 | 649 | 2,419 | 6,247 | 26,609 | 68,717 | 256,127 | 368,573 | 2,817,397 | 4,054,303 | 15,111,493 | 166,226,423 |
| -1 | -11 | -41 | -59 | -451 | -649 | -2,419 | -6,247 | -26,609 | -68,717 | -256,127 | -368,573 | -2,817,397 | -4,054,303 | -15,111,493 | -166,226,423 |
