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 23,050,531, 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 | 23,050,531 | |
| -1 | -23,050,531 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,050,531.
Example:
1 x 23,050,531 = 23,050,531
and
-1 x -23,050,531 = 23,050,531
Notice both answers equal 23,050,531
With that explanation out of the way, let's continue. Next, we take the number 23,050,531 and divide it by 2:
23,050,531 ÷ 2 = 11,525,265.5
If the quotient is a whole number, then 2 and 11,525,265.5 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 | 23,050,531 | |
| -1 | -23,050,531 |
Now, we try dividing 23,050,531 by 3:
23,050,531 ÷ 3 = 7,683,510.3333
If the quotient is a whole number, then 3 and 7,683,510.3333 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 | 23,050,531 | |
| -1 | -23,050,531 |
Let's try dividing by 4:
23,050,531 ÷ 4 = 5,762,632.75
If the quotient is a whole number, then 4 and 5,762,632.75 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 | 23,050,531 | |
| -1 | 23,050,531 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 49 | 113 | 161 | 181 | 791 | 1,127 | 1,267 | 2,599 | 4,163 | 5,537 | 8,869 | 18,193 | 20,453 | 29,141 | 127,351 | 143,171 | 203,987 | 470,419 | 1,002,197 | 3,292,933 | 23,050,531 |
| -1 | -7 | -23 | -49 | -113 | -161 | -181 | -791 | -1,127 | -1,267 | -2,599 | -4,163 | -5,537 | -8,869 | -18,193 | -20,453 | -29,141 | -127,351 | -143,171 | -203,987 | -470,419 | -1,002,197 | -3,292,933 | -23,050,531 |
