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 9,418,475, 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 | 9,418,475 | |
| -1 | -9,418,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,418,475.
Example:
1 x 9,418,475 = 9,418,475
and
-1 x -9,418,475 = 9,418,475
Notice both answers equal 9,418,475
With that explanation out of the way, let's continue. Next, we take the number 9,418,475 and divide it by 2:
9,418,475 ÷ 2 = 4,709,237.5
If the quotient is a whole number, then 2 and 4,709,237.5 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 | 9,418,475 | |
| -1 | -9,418,475 |
Now, we try dividing 9,418,475 by 3:
9,418,475 ÷ 3 = 3,139,491.6667
If the quotient is a whole number, then 3 and 3,139,491.6667 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 | 9,418,475 | |
| -1 | -9,418,475 |
Let's try dividing by 4:
9,418,475 ÷ 4 = 2,354,618.75
If the quotient is a whole number, then 4 and 2,354,618.75 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 | 9,418,475 | |
| -1 | 9,418,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 29 | 55 | 145 | 275 | 319 | 725 | 1,181 | 1,595 | 5,905 | 7,975 | 12,991 | 29,525 | 34,249 | 64,955 | 171,245 | 324,775 | 376,739 | 856,225 | 1,883,695 | 9,418,475 |
| -1 | -5 | -11 | -25 | -29 | -55 | -145 | -275 | -319 | -725 | -1,181 | -1,595 | -5,905 | -7,975 | -12,991 | -29,525 | -34,249 | -64,955 | -171,245 | -324,775 | -376,739 | -856,225 | -1,883,695 | -9,418,475 |
