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 166,736,635, 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 | 166,736,635 | |
| -1 | -166,736,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,736,635.
Example:
1 x 166,736,635 = 166,736,635
and
-1 x -166,736,635 = 166,736,635
Notice both answers equal 166,736,635
With that explanation out of the way, let's continue. Next, we take the number 166,736,635 and divide it by 2:
166,736,635 ÷ 2 = 83,368,317.5
If the quotient is a whole number, then 2 and 83,368,317.5 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 | 166,736,635 | |
| -1 | -166,736,635 |
Now, we try dividing 166,736,635 by 3:
166,736,635 ÷ 3 = 55,578,878.3333
If the quotient is a whole number, then 3 and 55,578,878.3333 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 | 166,736,635 | |
| -1 | -166,736,635 |
Let's try dividing by 4:
166,736,635 ÷ 4 = 41,684,158.75
If the quotient is a whole number, then 4 and 41,684,158.75 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 | 166,736,635 | |
| -1 | 166,736,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 1,567 | 1,637 | 7,835 | 8,185 | 20,371 | 21,281 | 101,855 | 106,405 | 2,565,179 | 12,825,895 | 33,347,327 | 166,736,635 |
| -1 | -5 | -13 | -65 | -1,567 | -1,637 | -7,835 | -8,185 | -20,371 | -21,281 | -101,855 | -106,405 | -2,565,179 | -12,825,895 | -33,347,327 | -166,736,635 |
