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 86,388,535, 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 | 86,388,535 | |
| -1 | -86,388,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 86,388,535.
Example:
1 x 86,388,535 = 86,388,535
and
-1 x -86,388,535 = 86,388,535
Notice both answers equal 86,388,535
With that explanation out of the way, let's continue. Next, we take the number 86,388,535 and divide it by 2:
86,388,535 ÷ 2 = 43,194,267.5
If the quotient is a whole number, then 2 and 43,194,267.5 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 | 86,388,535 | |
| -1 | -86,388,535 |
Now, we try dividing 86,388,535 by 3:
86,388,535 ÷ 3 = 28,796,178.3333
If the quotient is a whole number, then 3 and 28,796,178.3333 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 | 86,388,535 | |
| -1 | -86,388,535 |
Let's try dividing by 4:
86,388,535 ÷ 4 = 21,597,133.75
If the quotient is a whole number, then 4 and 21,597,133.75 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 | 86,388,535 | |
| -1 | 86,388,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 29 | 95 | 145 | 551 | 2,755 | 31,357 | 156,785 | 595,783 | 909,353 | 2,978,915 | 4,546,765 | 17,277,707 | 86,388,535 |
| -1 | -5 | -19 | -29 | -95 | -145 | -551 | -2,755 | -31,357 | -156,785 | -595,783 | -909,353 | -2,978,915 | -4,546,765 | -17,277,707 | -86,388,535 |
