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 23,024,615, 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 | 23,024,615 | |
| -1 | -23,024,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,024,615.
Example:
1 x 23,024,615 = 23,024,615
and
-1 x -23,024,615 = 23,024,615
Notice both answers equal 23,024,615
With that explanation out of the way, let's continue. Next, we take the number 23,024,615 and divide it by 2:
23,024,615 ÷ 2 = 11,512,307.5
If the quotient is a whole number, then 2 and 11,512,307.5 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 | 23,024,615 | |
| -1 | -23,024,615 |
Now, we try dividing 23,024,615 by 3:
23,024,615 ÷ 3 = 7,674,871.6667
If the quotient is a whole number, then 3 and 7,674,871.6667 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 | 23,024,615 | |
| -1 | -23,024,615 |
Let's try dividing by 4:
23,024,615 ÷ 4 = 5,756,153.75
If the quotient is a whole number, then 4 and 5,756,153.75 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 | 23,024,615 | |
| -1 | 23,024,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 83 | 109 | 415 | 509 | 545 | 2,545 | 9,047 | 42,247 | 45,235 | 55,481 | 211,235 | 277,405 | 4,604,923 | 23,024,615 |
| -1 | -5 | -83 | -109 | -415 | -509 | -545 | -2,545 | -9,047 | -42,247 | -45,235 | -55,481 | -211,235 | -277,405 | -4,604,923 | -23,024,615 |
