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 213,004,303, 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 | 213,004,303 | |
-1 | -213,004,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 213,004,303.
Example:
1 x 213,004,303 = 213,004,303
and
-1 x -213,004,303 = 213,004,303
Notice both answers equal 213,004,303
With that explanation out of the way, let's continue. Next, we take the number 213,004,303 and divide it by 2:
213,004,303 ÷ 2 = 106,502,151.5
If the quotient is a whole number, then 2 and 106,502,151.5 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 | 213,004,303 | |
-1 | -213,004,303 |
Now, we try dividing 213,004,303 by 3:
213,004,303 ÷ 3 = 71,001,434.3333
If the quotient is a whole number, then 3 and 71,001,434.3333 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 | 213,004,303 | |
-1 | -213,004,303 |
Let's try dividing by 4:
213,004,303 ÷ 4 = 53,251,075.75
If the quotient is a whole number, then 4 and 53,251,075.75 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 | 213,004,303 | |
-1 | 213,004,303 |
If you did it right, you will end up with this table:
1 | 79 | 2,696,257 | 213,004,303 |
-1 | -79 | -2,696,257 | -213,004,303 |
