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 84,282,835, 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 | 84,282,835 | |
| -1 | -84,282,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,282,835.
Example:
1 x 84,282,835 = 84,282,835
and
-1 x -84,282,835 = 84,282,835
Notice both answers equal 84,282,835
With that explanation out of the way, let's continue. Next, we take the number 84,282,835 and divide it by 2:
84,282,835 ÷ 2 = 42,141,417.5
If the quotient is a whole number, then 2 and 42,141,417.5 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 | 84,282,835 | |
| -1 | -84,282,835 |
Now, we try dividing 84,282,835 by 3:
84,282,835 ÷ 3 = 28,094,278.3333
If the quotient is a whole number, then 3 and 28,094,278.3333 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 | 84,282,835 | |
| -1 | -84,282,835 |
Let's try dividing by 4:
84,282,835 ÷ 4 = 21,070,708.75
If the quotient is a whole number, then 4 and 21,070,708.75 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 | 84,282,835 | |
| -1 | 84,282,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 169 | 455 | 845 | 1,183 | 5,915 | 14,249 | 71,245 | 99,743 | 185,237 | 498,715 | 926,185 | 1,296,659 | 2,408,081 | 6,483,295 | 12,040,405 | 16,856,567 | 84,282,835 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -169 | -455 | -845 | -1,183 | -5,915 | -14,249 | -71,245 | -99,743 | -185,237 | -498,715 | -926,185 | -1,296,659 | -2,408,081 | -6,483,295 | -12,040,405 | -16,856,567 | -84,282,835 |
