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 166,043,221, 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 | 166,043,221 | |
-1 | -166,043,221 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,043,221.
Example:
1 x 166,043,221 = 166,043,221
and
-1 x -166,043,221 = 166,043,221
Notice both answers equal 166,043,221
With that explanation out of the way, let's continue. Next, we take the number 166,043,221 and divide it by 2:
166,043,221 ÷ 2 = 83,021,610.5
If the quotient is a whole number, then 2 and 83,021,610.5 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 | 166,043,221 | |
-1 | -166,043,221 |
Now, we try dividing 166,043,221 by 3:
166,043,221 ÷ 3 = 55,347,740.3333
If the quotient is a whole number, then 3 and 55,347,740.3333 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 | 166,043,221 | |
-1 | -166,043,221 |
Let's try dividing by 4:
166,043,221 ÷ 4 = 41,510,805.25
If the quotient is a whole number, then 4 and 41,510,805.25 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 | 166,043,221 | |
-1 | 166,043,221 |
If you did it right, you will end up with this table:
1 | 521 | 318,701 | 166,043,221 |
-1 | -521 | -318,701 | -166,043,221 |
