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 23,166,073, 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 | 23,166,073 | |
| -1 | -23,166,073 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,166,073.
Example:
1 x 23,166,073 = 23,166,073
and
-1 x -23,166,073 = 23,166,073
Notice both answers equal 23,166,073
With that explanation out of the way, let's continue. Next, we take the number 23,166,073 and divide it by 2:
23,166,073 ÷ 2 = 11,583,036.5
If the quotient is a whole number, then 2 and 11,583,036.5 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 | 23,166,073 | |
| -1 | -23,166,073 |
Now, we try dividing 23,166,073 by 3:
23,166,073 ÷ 3 = 7,722,024.3333
If the quotient is a whole number, then 3 and 7,722,024.3333 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 | 23,166,073 | |
| -1 | -23,166,073 |
Let's try dividing by 4:
23,166,073 ÷ 4 = 5,791,518.25
If the quotient is a whole number, then 4 and 5,791,518.25 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 | 23,166,073 | |
| -1 | 23,166,073 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 49 | 133 | 149 | 167 | 931 | 1,043 | 1,169 | 2,831 | 3,173 | 7,301 | 8,183 | 19,817 | 22,211 | 24,883 | 138,719 | 155,477 | 174,181 | 472,777 | 1,219,267 | 3,309,439 | 23,166,073 |
| -1 | -7 | -19 | -49 | -133 | -149 | -167 | -931 | -1,043 | -1,169 | -2,831 | -3,173 | -7,301 | -8,183 | -19,817 | -22,211 | -24,883 | -138,719 | -155,477 | -174,181 | -472,777 | -1,219,267 | -3,309,439 | -23,166,073 |
