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 1,670,249, 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 | 1,670,249 | |
| -1 | -1,670,249 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,670,249.
Example:
1 x 1,670,249 = 1,670,249
and
-1 x -1,670,249 = 1,670,249
Notice both answers equal 1,670,249
With that explanation out of the way, let's continue. Next, we take the number 1,670,249 and divide it by 2:
1,670,249 ÷ 2 = 835,124.5
If the quotient is a whole number, then 2 and 835,124.5 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 | 1,670,249 | |
| -1 | -1,670,249 |
Now, we try dividing 1,670,249 by 3:
1,670,249 ÷ 3 = 556,749.6667
If the quotient is a whole number, then 3 and 556,749.6667 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 | 1,670,249 | |
| -1 | -1,670,249 |
Let's try dividing by 4:
1,670,249 ÷ 4 = 417,562.25
If the quotient is a whole number, then 4 and 417,562.25 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 | 1,670,249 | |
| -1 | 1,670,249 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 43 | 179 | 217 | 301 | 1,253 | 1,333 | 5,549 | 7,697 | 9,331 | 38,843 | 53,879 | 238,607 | 1,670,249 |
| -1 | -7 | -31 | -43 | -179 | -217 | -301 | -1,253 | -1,333 | -5,549 | -7,697 | -9,331 | -38,843 | -53,879 | -238,607 | -1,670,249 |
