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 166,536,535, 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 | 166,536,535 | |
| -1 | -166,536,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,536,535.
Example:
1 x 166,536,535 = 166,536,535
and
-1 x -166,536,535 = 166,536,535
Notice both answers equal 166,536,535
With that explanation out of the way, let's continue. Next, we take the number 166,536,535 and divide it by 2:
166,536,535 ÷ 2 = 83,268,267.5
If the quotient is a whole number, then 2 and 83,268,267.5 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 | 166,536,535 | |
| -1 | -166,536,535 |
Now, we try dividing 166,536,535 by 3:
166,536,535 ÷ 3 = 55,512,178.3333
If the quotient is a whole number, then 3 and 55,512,178.3333 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 | 166,536,535 | |
| -1 | -166,536,535 |
Let's try dividing by 4:
166,536,535 ÷ 4 = 41,634,133.75
If the quotient is a whole number, then 4 and 41,634,133.75 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 | 166,536,535 | |
| -1 | 166,536,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 71 | 121 | 355 | 605 | 781 | 3,877 | 3,905 | 8,591 | 19,385 | 42,647 | 42,955 | 213,235 | 275,267 | 469,117 | 1,376,335 | 2,345,585 | 3,027,937 | 15,139,685 | 33,307,307 | 166,536,535 |
| -1 | -5 | -11 | -55 | -71 | -121 | -355 | -605 | -781 | -3,877 | -3,905 | -8,591 | -19,385 | -42,647 | -42,955 | -213,235 | -275,267 | -469,117 | -1,376,335 | -2,345,585 | -3,027,937 | -15,139,685 | -33,307,307 | -166,536,535 |
