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 318,701,573, 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 | 318,701,573 | |
-1 | -318,701,573 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 318,701,573.
Example:
1 x 318,701,573 = 318,701,573
and
-1 x -318,701,573 = 318,701,573
Notice both answers equal 318,701,573
With that explanation out of the way, let's continue. Next, we take the number 318,701,573 and divide it by 2:
318,701,573 ÷ 2 = 159,350,786.5
If the quotient is a whole number, then 2 and 159,350,786.5 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 | 318,701,573 | |
-1 | -318,701,573 |
Now, we try dividing 318,701,573 by 3:
318,701,573 ÷ 3 = 106,233,857.6667
If the quotient is a whole number, then 3 and 106,233,857.6667 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 | 318,701,573 | |
-1 | -318,701,573 |
Let's try dividing by 4:
318,701,573 ÷ 4 = 79,675,393.25
If the quotient is a whole number, then 4 and 79,675,393.25 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 | 318,701,573 | |
-1 | 318,701,573 |
If you did it right, you will end up with this table:
1 | 19 | 16,773,767 | 318,701,573 |
-1 | -19 | -16,773,767 | -318,701,573 |
