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 166,625,263, 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 | 166,625,263 | |
| -1 | -166,625,263 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,625,263.
Example:
1 x 166,625,263 = 166,625,263
and
-1 x -166,625,263 = 166,625,263
Notice both answers equal 166,625,263
With that explanation out of the way, let's continue. Next, we take the number 166,625,263 and divide it by 2:
166,625,263 ÷ 2 = 83,312,631.5
If the quotient is a whole number, then 2 and 83,312,631.5 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 | 166,625,263 | |
| -1 | -166,625,263 |
Now, we try dividing 166,625,263 by 3:
166,625,263 ÷ 3 = 55,541,754.3333
If the quotient is a whole number, then 3 and 55,541,754.3333 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 | 166,625,263 | |
| -1 | -166,625,263 |
Let's try dividing by 4:
166,625,263 ÷ 4 = 41,656,315.75
If the quotient is a whole number, then 4 and 41,656,315.75 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 | 166,625,263 | |
| -1 | 166,625,263 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 103 | 413 | 721 | 3,917 | 6,077 | 27,419 | 42,539 | 231,103 | 403,451 | 1,617,721 | 2,824,157 | 23,803,609 | 166,625,263 |
| -1 | -7 | -59 | -103 | -413 | -721 | -3,917 | -6,077 | -27,419 | -42,539 | -231,103 | -403,451 | -1,617,721 | -2,824,157 | -23,803,609 | -166,625,263 |
