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 83,816,177, 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 | 83,816,177 | |
| -1 | -83,816,177 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 83,816,177.
Example:
1 x 83,816,177 = 83,816,177
and
-1 x -83,816,177 = 83,816,177
Notice both answers equal 83,816,177
With that explanation out of the way, let's continue. Next, we take the number 83,816,177 and divide it by 2:
83,816,177 ÷ 2 = 41,908,088.5
If the quotient is a whole number, then 2 and 41,908,088.5 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 | 83,816,177 | |
| -1 | -83,816,177 |
Now, we try dividing 83,816,177 by 3:
83,816,177 ÷ 3 = 27,938,725.6667
If the quotient is a whole number, then 3 and 27,938,725.6667 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 | 83,816,177 | |
| -1 | -83,816,177 |
Let's try dividing by 4:
83,816,177 ÷ 4 = 20,954,044.25
If the quotient is a whole number, then 4 and 20,954,044.25 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 | 83,816,177 | |
| -1 | 83,816,177 |
If you did it right, you will end up with this table:
| 1 | 29 | 41 | 157 | 449 | 1,189 | 4,553 | 6,437 | 13,021 | 18,409 | 70,493 | 186,673 | 533,861 | 2,044,297 | 2,890,213 | 83,816,177 |
| -1 | -29 | -41 | -157 | -449 | -1,189 | -4,553 | -6,437 | -13,021 | -18,409 | -70,493 | -186,673 | -533,861 | -2,044,297 | -2,890,213 | -83,816,177 |
