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 84,062,111, 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 | 84,062,111 | |
| -1 | -84,062,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,062,111.
Example:
1 x 84,062,111 = 84,062,111
and
-1 x -84,062,111 = 84,062,111
Notice both answers equal 84,062,111
With that explanation out of the way, let's continue. Next, we take the number 84,062,111 and divide it by 2:
84,062,111 ÷ 2 = 42,031,055.5
If the quotient is a whole number, then 2 and 42,031,055.5 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 | 84,062,111 | |
| -1 | -84,062,111 |
Now, we try dividing 84,062,111 by 3:
84,062,111 ÷ 3 = 28,020,703.6667
If the quotient is a whole number, then 3 and 28,020,703.6667 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 | 84,062,111 | |
| -1 | -84,062,111 |
Let's try dividing by 4:
84,062,111 ÷ 4 = 21,015,527.75
If the quotient is a whole number, then 4 and 21,015,527.75 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 | 84,062,111 | |
| -1 | 84,062,111 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 103 | 217 | 721 | 3,193 | 3,761 | 22,351 | 26,327 | 116,591 | 387,383 | 816,137 | 2,711,681 | 12,008,873 | 84,062,111 |
| -1 | -7 | -31 | -103 | -217 | -721 | -3,193 | -3,761 | -22,351 | -26,327 | -116,591 | -387,383 | -816,137 | -2,711,681 | -12,008,873 | -84,062,111 |
