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 186,123,653, 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 | 186,123,653 | |
| -1 | -186,123,653 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 186,123,653.
Example:
1 x 186,123,653 = 186,123,653
and
-1 x -186,123,653 = 186,123,653
Notice both answers equal 186,123,653
With that explanation out of the way, let's continue. Next, we take the number 186,123,653 and divide it by 2:
186,123,653 ÷ 2 = 93,061,826.5
If the quotient is a whole number, then 2 and 93,061,826.5 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 | 186,123,653 | |
| -1 | -186,123,653 |
Now, we try dividing 186,123,653 by 3:
186,123,653 ÷ 3 = 62,041,217.6667
If the quotient is a whole number, then 3 and 62,041,217.6667 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 | 186,123,653 | |
| -1 | -186,123,653 |
Let's try dividing by 4:
186,123,653 ÷ 4 = 46,530,913.25
If the quotient is a whole number, then 4 and 46,530,913.25 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 | 186,123,653 | |
| -1 | 186,123,653 |
If you did it right, you will end up with this table:
| 1 | 29 | 37 | 89 | 1,073 | 1,949 | 2,581 | 3,293 | 56,521 | 72,113 | 95,497 | 173,461 | 2,091,277 | 5,030,369 | 6,418,057 | 186,123,653 |
| -1 | -29 | -37 | -89 | -1,073 | -1,949 | -2,581 | -3,293 | -56,521 | -72,113 | -95,497 | -173,461 | -2,091,277 | -5,030,369 | -6,418,057 | -186,123,653 |
