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 142,161,833, 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 | 142,161,833 | |
| -1 | -142,161,833 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,161,833.
Example:
1 x 142,161,833 = 142,161,833
and
-1 x -142,161,833 = 142,161,833
Notice both answers equal 142,161,833
With that explanation out of the way, let's continue. Next, we take the number 142,161,833 and divide it by 2:
142,161,833 ÷ 2 = 71,080,916.5
If the quotient is a whole number, then 2 and 71,080,916.5 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 | 142,161,833 | |
| -1 | -142,161,833 |
Now, we try dividing 142,161,833 by 3:
142,161,833 ÷ 3 = 47,387,277.6667
If the quotient is a whole number, then 3 and 47,387,277.6667 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 | 142,161,833 | |
| -1 | -142,161,833 |
Let's try dividing by 4:
142,161,833 ÷ 4 = 35,540,458.25
If the quotient is a whole number, then 4 and 35,540,458.25 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 | 142,161,833 | |
| -1 | 142,161,833 |
If you did it right, you will end up with this table:
| 1 | 11 | 109 | 139 | 853 | 1,199 | 1,529 | 9,383 | 15,151 | 92,977 | 118,567 | 166,661 | 1,022,747 | 1,304,237 | 12,923,803 | 142,161,833 |
| -1 | -11 | -109 | -139 | -853 | -1,199 | -1,529 | -9,383 | -15,151 | -92,977 | -118,567 | -166,661 | -1,022,747 | -1,304,237 | -12,923,803 | -142,161,833 |
