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 187,211,719, 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 | 187,211,719 | |
-1 | -187,211,719 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 187,211,719.
Example:
1 x 187,211,719 = 187,211,719
and
-1 x -187,211,719 = 187,211,719
Notice both answers equal 187,211,719
With that explanation out of the way, let's continue. Next, we take the number 187,211,719 and divide it by 2:
187,211,719 ÷ 2 = 93,605,859.5
If the quotient is a whole number, then 2 and 93,605,859.5 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 | 187,211,719 | |
-1 | -187,211,719 |
Now, we try dividing 187,211,719 by 3:
187,211,719 ÷ 3 = 62,403,906.3333
If the quotient is a whole number, then 3 and 62,403,906.3333 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 | 187,211,719 | |
-1 | -187,211,719 |
Let's try dividing by 4:
187,211,719 ÷ 4 = 46,802,929.75
If the quotient is a whole number, then 4 and 46,802,929.75 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 | 187,211,719 | |
-1 | 187,211,719 |
If you did it right, you will end up with this table:
1 | 3,907 | 47,917 | 187,211,719 |
-1 | -3,907 | -47,917 | -187,211,719 |
