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 23,774,795, 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 | 23,774,795 | |
| -1 | -23,774,795 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,774,795.
Example:
1 x 23,774,795 = 23,774,795
and
-1 x -23,774,795 = 23,774,795
Notice both answers equal 23,774,795
With that explanation out of the way, let's continue. Next, we take the number 23,774,795 and divide it by 2:
23,774,795 ÷ 2 = 11,887,397.5
If the quotient is a whole number, then 2 and 11,887,397.5 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 | 23,774,795 | |
| -1 | -23,774,795 |
Now, we try dividing 23,774,795 by 3:
23,774,795 ÷ 3 = 7,924,931.6667
If the quotient is a whole number, then 3 and 7,924,931.6667 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 | 23,774,795 | |
| -1 | -23,774,795 |
Let's try dividing by 4:
23,774,795 ÷ 4 = 5,943,698.75
If the quotient is a whole number, then 4 and 5,943,698.75 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 | 23,774,795 | |
| -1 | 23,774,795 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 55 | 95 | 209 | 1,045 | 22,751 | 113,755 | 250,261 | 432,269 | 1,251,305 | 2,161,345 | 4,754,959 | 23,774,795 |
| -1 | -5 | -11 | -19 | -55 | -95 | -209 | -1,045 | -22,751 | -113,755 | -250,261 | -432,269 | -1,251,305 | -2,161,345 | -4,754,959 | -23,774,795 |
