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 23,165,611, 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 | 23,165,611 | |
| -1 | -23,165,611 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,165,611.
Example:
1 x 23,165,611 = 23,165,611
and
-1 x -23,165,611 = 23,165,611
Notice both answers equal 23,165,611
With that explanation out of the way, let's continue. Next, we take the number 23,165,611 and divide it by 2:
23,165,611 ÷ 2 = 11,582,805.5
If the quotient is a whole number, then 2 and 11,582,805.5 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 | 23,165,611 | |
| -1 | -23,165,611 |
Now, we try dividing 23,165,611 by 3:
23,165,611 ÷ 3 = 7,721,870.3333
If the quotient is a whole number, then 3 and 7,721,870.3333 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 | 23,165,611 | |
| -1 | -23,165,611 |
Let's try dividing by 4:
23,165,611 ÷ 4 = 5,791,402.75
If the quotient is a whole number, then 4 and 5,791,402.75 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 | 23,165,611 | |
| -1 | 23,165,611 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 53 | 119 | 371 | 901 | 3,673 | 6,307 | 25,711 | 62,441 | 194,669 | 437,087 | 1,362,683 | 3,309,373 | 23,165,611 |
| -1 | -7 | -17 | -53 | -119 | -371 | -901 | -3,673 | -6,307 | -25,711 | -62,441 | -194,669 | -437,087 | -1,362,683 | -3,309,373 | -23,165,611 |
