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 316,221,259, 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 | 316,221,259 | |
-1 | -316,221,259 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 316,221,259.
Example:
1 x 316,221,259 = 316,221,259
and
-1 x -316,221,259 = 316,221,259
Notice both answers equal 316,221,259
With that explanation out of the way, let's continue. Next, we take the number 316,221,259 and divide it by 2:
316,221,259 ÷ 2 = 158,110,629.5
If the quotient is a whole number, then 2 and 158,110,629.5 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 | 316,221,259 | |
-1 | -316,221,259 |
Now, we try dividing 316,221,259 by 3:
316,221,259 ÷ 3 = 105,407,086.3333
If the quotient is a whole number, then 3 and 105,407,086.3333 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 | 316,221,259 | |
-1 | -316,221,259 |
Let's try dividing by 4:
316,221,259 ÷ 4 = 79,055,314.75
If the quotient is a whole number, then 4 and 79,055,314.75 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 | 316,221,259 | |
-1 | 316,221,259 |
If you did it right, you will end up with this table:
1 | 769 | 411,211 | 316,221,259 |
-1 | -769 | -411,211 | -316,221,259 |
