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 166,526,545, 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 | 166,526,545 | |
| -1 | -166,526,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,526,545.
Example:
1 x 166,526,545 = 166,526,545
and
-1 x -166,526,545 = 166,526,545
Notice both answers equal 166,526,545
With that explanation out of the way, let's continue. Next, we take the number 166,526,545 and divide it by 2:
166,526,545 ÷ 2 = 83,263,272.5
If the quotient is a whole number, then 2 and 83,263,272.5 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 | 166,526,545 | |
| -1 | -166,526,545 |
Now, we try dividing 166,526,545 by 3:
166,526,545 ÷ 3 = 55,508,848.3333
If the quotient is a whole number, then 3 and 55,508,848.3333 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 | 166,526,545 | |
| -1 | -166,526,545 |
Let's try dividing by 4:
166,526,545 ÷ 4 = 41,631,636.25
If the quotient is a whole number, then 4 and 41,631,636.25 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 | 166,526,545 | |
| -1 | 166,526,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 131 | 655 | 2,489 | 12,445 | 13,381 | 66,905 | 254,239 | 1,271,195 | 1,752,911 | 8,764,555 | 33,305,309 | 166,526,545 |
| -1 | -5 | -19 | -95 | -131 | -655 | -2,489 | -12,445 | -13,381 | -66,905 | -254,239 | -1,271,195 | -1,752,911 | -8,764,555 | -33,305,309 | -166,526,545 |
