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 166,252,267, 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 | 166,252,267 | |
| -1 | -166,252,267 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,252,267.
Example:
1 x 166,252,267 = 166,252,267
and
-1 x -166,252,267 = 166,252,267
Notice both answers equal 166,252,267
With that explanation out of the way, let's continue. Next, we take the number 166,252,267 and divide it by 2:
166,252,267 ÷ 2 = 83,126,133.5
If the quotient is a whole number, then 2 and 83,126,133.5 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 | 166,252,267 | |
| -1 | -166,252,267 |
Now, we try dividing 166,252,267 by 3:
166,252,267 ÷ 3 = 55,417,422.3333
If the quotient is a whole number, then 3 and 55,417,422.3333 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 | 166,252,267 | |
| -1 | -166,252,267 |
Let's try dividing by 4:
166,252,267 ÷ 4 = 41,563,066.75
If the quotient is a whole number, then 4 and 41,563,066.75 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 | 166,252,267 | |
| -1 | 166,252,267 |
If you did it right, you will end up with this table:
| 1 | 61 | 89 | 113 | 271 | 5,429 | 6,893 | 10,057 | 16,531 | 24,119 | 30,623 | 613,477 | 1,471,259 | 1,868,003 | 2,725,447 | 166,252,267 |
| -1 | -61 | -89 | -113 | -271 | -5,429 | -6,893 | -10,057 | -16,531 | -24,119 | -30,623 | -613,477 | -1,471,259 | -1,868,003 | -2,725,447 | -166,252,267 |
