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 1,494,493, 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 | 1,494,493 | |
| -1 | -1,494,493 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,494,493.
Example:
1 x 1,494,493 = 1,494,493
and
-1 x -1,494,493 = 1,494,493
Notice both answers equal 1,494,493
With that explanation out of the way, let's continue. Next, we take the number 1,494,493 and divide it by 2:
1,494,493 ÷ 2 = 747,246.5
If the quotient is a whole number, then 2 and 747,246.5 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 | 1,494,493 | |
| -1 | -1,494,493 |
Now, we try dividing 1,494,493 by 3:
1,494,493 ÷ 3 = 498,164.3333
If the quotient is a whole number, then 3 and 498,164.3333 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 | 1,494,493 | |
| -1 | -1,494,493 |
Let's try dividing by 4:
1,494,493 ÷ 4 = 373,623.25
If the quotient is a whole number, then 4 and 373,623.25 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 | 1,494,493 | |
| -1 | 1,494,493 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 1,493 | 10,451 | 16,423 | 19,409 | 114,961 | 135,863 | 213,499 | 1,494,493 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -1,493 | -10,451 | -16,423 | -19,409 | -114,961 | -135,863 | -213,499 | -1,494,493 |
