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 166,949,645, 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 | 166,949,645 | |
| -1 | -166,949,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,949,645.
Example:
1 x 166,949,645 = 166,949,645
and
-1 x -166,949,645 = 166,949,645
Notice both answers equal 166,949,645
With that explanation out of the way, let's continue. Next, we take the number 166,949,645 and divide it by 2:
166,949,645 ÷ 2 = 83,474,822.5
If the quotient is a whole number, then 2 and 83,474,822.5 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 | 166,949,645 | |
| -1 | -166,949,645 |
Now, we try dividing 166,949,645 by 3:
166,949,645 ÷ 3 = 55,649,881.6667
If the quotient is a whole number, then 3 and 55,649,881.6667 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 | 166,949,645 | |
| -1 | -166,949,645 |
Let's try dividing by 4:
166,949,645 ÷ 4 = 41,737,411.25
If the quotient is a whole number, then 4 and 41,737,411.25 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 | 166,949,645 | |
| -1 | 166,949,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 295 | 433 | 1,307 | 2,165 | 6,535 | 25,547 | 77,113 | 127,735 | 385,565 | 565,931 | 2,829,655 | 33,389,929 | 166,949,645 |
| -1 | -5 | -59 | -295 | -433 | -1,307 | -2,165 | -6,535 | -25,547 | -77,113 | -127,735 | -385,565 | -565,931 | -2,829,655 | -33,389,929 | -166,949,645 |
