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 347,581,789, 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 | 347,581,789 | |
-1 | -347,581,789 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 347,581,789.
Example:
1 x 347,581,789 = 347,581,789
and
-1 x -347,581,789 = 347,581,789
Notice both answers equal 347,581,789
With that explanation out of the way, let's continue. Next, we take the number 347,581,789 and divide it by 2:
347,581,789 ÷ 2 = 173,790,894.5
If the quotient is a whole number, then 2 and 173,790,894.5 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 | 347,581,789 | |
-1 | -347,581,789 |
Now, we try dividing 347,581,789 by 3:
347,581,789 ÷ 3 = 115,860,596.3333
If the quotient is a whole number, then 3 and 115,860,596.3333 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 | 347,581,789 | |
-1 | -347,581,789 |
Let's try dividing by 4:
347,581,789 ÷ 4 = 86,895,447.25
If the quotient is a whole number, then 4 and 86,895,447.25 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 | 347,581,789 | |
-1 | 347,581,789 |
If you did it right, you will end up with this table:
1 | 1,487 | 233,747 | 347,581,789 |
-1 | -1,487 | -233,747 | -347,581,789 |
