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 666,361,351, 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 | 666,361,351 | |
-1 | -666,361,351 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 666,361,351.
Example:
1 x 666,361,351 = 666,361,351
and
-1 x -666,361,351 = 666,361,351
Notice both answers equal 666,361,351
With that explanation out of the way, let's continue. Next, we take the number 666,361,351 and divide it by 2:
666,361,351 ÷ 2 = 333,180,675.5
If the quotient is a whole number, then 2 and 333,180,675.5 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 | 666,361,351 | |
-1 | -666,361,351 |
Now, we try dividing 666,361,351 by 3:
666,361,351 ÷ 3 = 222,120,450.3333
If the quotient is a whole number, then 3 and 222,120,450.3333 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 | 666,361,351 | |
-1 | -666,361,351 |
Let's try dividing by 4:
666,361,351 ÷ 4 = 166,590,337.75
If the quotient is a whole number, then 4 and 166,590,337.75 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 | 666,361,351 | |
-1 | 666,361,351 |
If you did it right, you will end up with this table:
1 | 311 | 2,142,641 | 666,361,351 |
-1 | -311 | -2,142,641 | -666,361,351 |
