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 18,954,775, 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 | 18,954,775 | |
| -1 | -18,954,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,954,775.
Example:
1 x 18,954,775 = 18,954,775
and
-1 x -18,954,775 = 18,954,775
Notice both answers equal 18,954,775
With that explanation out of the way, let's continue. Next, we take the number 18,954,775 and divide it by 2:
18,954,775 ÷ 2 = 9,477,387.5
If the quotient is a whole number, then 2 and 9,477,387.5 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 | 18,954,775 | |
| -1 | -18,954,775 |
Now, we try dividing 18,954,775 by 3:
18,954,775 ÷ 3 = 6,318,258.3333
If the quotient is a whole number, then 3 and 6,318,258.3333 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 | 18,954,775 | |
| -1 | -18,954,775 |
Let's try dividing by 4:
18,954,775 ÷ 4 = 4,738,693.75
If the quotient is a whole number, then 4 and 4,738,693.75 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 | 18,954,775 | |
| -1 | 18,954,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 89 | 175 | 445 | 623 | 1,217 | 2,225 | 3,115 | 6,085 | 8,519 | 15,575 | 30,425 | 42,595 | 108,313 | 212,975 | 541,565 | 758,191 | 2,707,825 | 3,790,955 | 18,954,775 |
| -1 | -5 | -7 | -25 | -35 | -89 | -175 | -445 | -623 | -1,217 | -2,225 | -3,115 | -6,085 | -8,519 | -15,575 | -30,425 | -42,595 | -108,313 | -212,975 | -541,565 | -758,191 | -2,707,825 | -3,790,955 | -18,954,775 |
