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 802,212,427, 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 | 802,212,427 | |
-1 | -802,212,427 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 802,212,427.
Example:
1 x 802,212,427 = 802,212,427
and
-1 x -802,212,427 = 802,212,427
Notice both answers equal 802,212,427
With that explanation out of the way, let's continue. Next, we take the number 802,212,427 and divide it by 2:
802,212,427 ÷ 2 = 401,106,213.5
If the quotient is a whole number, then 2 and 401,106,213.5 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 | 802,212,427 | |
-1 | -802,212,427 |
Now, we try dividing 802,212,427 by 3:
802,212,427 ÷ 3 = 267,404,142.3333
If the quotient is a whole number, then 3 and 267,404,142.3333 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 | 802,212,427 | |
-1 | -802,212,427 |
Let's try dividing by 4:
802,212,427 ÷ 4 = 200,553,106.75
If the quotient is a whole number, then 4 and 200,553,106.75 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 | 802,212,427 | |
-1 | 802,212,427 |
If you did it right, you will end up with this table:
1 | 313 | 2,562,979 | 802,212,427 |
-1 | -313 | -2,562,979 | -802,212,427 |
