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 86,184,619, 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 | 86,184,619 | |
-1 | -86,184,619 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 86,184,619.
Example:
1 x 86,184,619 = 86,184,619
and
-1 x -86,184,619 = 86,184,619
Notice both answers equal 86,184,619
With that explanation out of the way, let's continue. Next, we take the number 86,184,619 and divide it by 2:
86,184,619 ÷ 2 = 43,092,309.5
If the quotient is a whole number, then 2 and 43,092,309.5 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 | 86,184,619 | |
-1 | -86,184,619 |
Now, we try dividing 86,184,619 by 3:
86,184,619 ÷ 3 = 28,728,206.3333
If the quotient is a whole number, then 3 and 28,728,206.3333 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 | 86,184,619 | |
-1 | -86,184,619 |
Let's try dividing by 4:
86,184,619 ÷ 4 = 21,546,154.75
If the quotient is a whole number, then 4 and 21,546,154.75 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 | 86,184,619 | |
-1 | 86,184,619 |
If you did it right, you will end up with this table:
1 | 31 | 2,780,149 | 86,184,619 |
-1 | -31 | -2,780,149 | -86,184,619 |
