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 23,460,385, 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 | 23,460,385 | |
| -1 | -23,460,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,460,385.
Example:
1 x 23,460,385 = 23,460,385
and
-1 x -23,460,385 = 23,460,385
Notice both answers equal 23,460,385
With that explanation out of the way, let's continue. Next, we take the number 23,460,385 and divide it by 2:
23,460,385 ÷ 2 = 11,730,192.5
If the quotient is a whole number, then 2 and 11,730,192.5 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 | 23,460,385 | |
| -1 | -23,460,385 |
Now, we try dividing 23,460,385 by 3:
23,460,385 ÷ 3 = 7,820,128.3333
If the quotient is a whole number, then 3 and 7,820,128.3333 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 | 23,460,385 | |
| -1 | -23,460,385 |
Let's try dividing by 4:
23,460,385 ÷ 4 = 5,865,096.25
If the quotient is a whole number, then 4 and 5,865,096.25 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 | 23,460,385 | |
| -1 | 23,460,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 67 | 335 | 871 | 4,355 | 5,387 | 26,935 | 70,031 | 350,155 | 360,929 | 1,804,645 | 4,692,077 | 23,460,385 |
| -1 | -5 | -13 | -65 | -67 | -335 | -871 | -4,355 | -5,387 | -26,935 | -70,031 | -350,155 | -360,929 | -1,804,645 | -4,692,077 | -23,460,385 |
