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 166,407,833, 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 | 166,407,833 | |
| -1 | -166,407,833 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,407,833.
Example:
1 x 166,407,833 = 166,407,833
and
-1 x -166,407,833 = 166,407,833
Notice both answers equal 166,407,833
With that explanation out of the way, let's continue. Next, we take the number 166,407,833 and divide it by 2:
166,407,833 ÷ 2 = 83,203,916.5
If the quotient is a whole number, then 2 and 83,203,916.5 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 | 166,407,833 | |
| -1 | -166,407,833 |
Now, we try dividing 166,407,833 by 3:
166,407,833 ÷ 3 = 55,469,277.6667
If the quotient is a whole number, then 3 and 55,469,277.6667 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 | 166,407,833 | |
| -1 | -166,407,833 |
Let's try dividing by 4:
166,407,833 ÷ 4 = 41,601,958.25
If the quotient is a whole number, then 4 and 41,601,958.25 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 | 166,407,833 | |
| -1 | 166,407,833 |
If you did it right, you will end up with this table:
| 1 | 19 | 37 | 67 | 703 | 1,273 | 2,479 | 3,533 | 47,101 | 67,127 | 130,721 | 236,711 | 2,483,699 | 4,497,509 | 8,758,307 | 166,407,833 |
| -1 | -19 | -37 | -67 | -703 | -1,273 | -2,479 | -3,533 | -47,101 | -67,127 | -130,721 | -236,711 | -2,483,699 | -4,497,509 | -8,758,307 | -166,407,833 |
