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 23,152,051, 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 | 23,152,051 | |
| -1 | -23,152,051 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,152,051.
Example:
1 x 23,152,051 = 23,152,051
and
-1 x -23,152,051 = 23,152,051
Notice both answers equal 23,152,051
With that explanation out of the way, let's continue. Next, we take the number 23,152,051 and divide it by 2:
23,152,051 ÷ 2 = 11,576,025.5
If the quotient is a whole number, then 2 and 11,576,025.5 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 | 23,152,051 | |
| -1 | -23,152,051 |
Now, we try dividing 23,152,051 by 3:
23,152,051 ÷ 3 = 7,717,350.3333
If the quotient is a whole number, then 3 and 7,717,350.3333 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 | 23,152,051 | |
| -1 | -23,152,051 |
Let's try dividing by 4:
23,152,051 ÷ 4 = 5,788,012.75
If the quotient is a whole number, then 4 and 5,788,012.75 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 | 23,152,051 | |
| -1 | 23,152,051 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 67 | 247 | 871 | 1,273 | 1,399 | 16,549 | 18,187 | 26,581 | 93,733 | 345,553 | 1,218,529 | 1,780,927 | 23,152,051 |
| -1 | -13 | -19 | -67 | -247 | -871 | -1,273 | -1,399 | -16,549 | -18,187 | -26,581 | -93,733 | -345,553 | -1,218,529 | -1,780,927 | -23,152,051 |
