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 166,700,113, 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 | 166,700,113 | |
| -1 | -166,700,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,700,113.
Example:
1 x 166,700,113 = 166,700,113
and
-1 x -166,700,113 = 166,700,113
Notice both answers equal 166,700,113
With that explanation out of the way, let's continue. Next, we take the number 166,700,113 and divide it by 2:
166,700,113 ÷ 2 = 83,350,056.5
If the quotient is a whole number, then 2 and 83,350,056.5 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 | 166,700,113 | |
| -1 | -166,700,113 |
Now, we try dividing 166,700,113 by 3:
166,700,113 ÷ 3 = 55,566,704.3333
If the quotient is a whole number, then 3 and 55,566,704.3333 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 | 166,700,113 | |
| -1 | -166,700,113 |
Let's try dividing by 4:
166,700,113 ÷ 4 = 41,675,028.25
If the quotient is a whole number, then 4 and 41,675,028.25 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 | 166,700,113 | |
| -1 | 166,700,113 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 31 | 289 | 391 | 527 | 713 | 809 | 6,647 | 8,959 | 12,121 | 13,753 | 18,607 | 25,079 | 206,057 | 233,801 | 316,319 | 426,343 | 576,817 | 5,377,423 | 7,247,831 | 9,805,889 | 166,700,113 |
| -1 | -17 | -23 | -31 | -289 | -391 | -527 | -713 | -809 | -6,647 | -8,959 | -12,121 | -13,753 | -18,607 | -25,079 | -206,057 | -233,801 | -316,319 | -426,343 | -576,817 | -5,377,423 | -7,247,831 | -9,805,889 | -166,700,113 |
