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 1,764,245, 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 | 1,764,245 | |
| -1 | -1,764,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,764,245.
Example:
1 x 1,764,245 = 1,764,245
and
-1 x -1,764,245 = 1,764,245
Notice both answers equal 1,764,245
With that explanation out of the way, let's continue. Next, we take the number 1,764,245 and divide it by 2:
1,764,245 ÷ 2 = 882,122.5
If the quotient is a whole number, then 2 and 882,122.5 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 | 1,764,245 | |
| -1 | -1,764,245 |
Now, we try dividing 1,764,245 by 3:
1,764,245 ÷ 3 = 588,081.6667
If the quotient is a whole number, then 3 and 588,081.6667 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 | 1,764,245 | |
| -1 | -1,764,245 |
Let's try dividing by 4:
1,764,245 ÷ 4 = 441,061.25
If the quotient is a whole number, then 4 and 441,061.25 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 | 1,764,245 | |
| -1 | 1,764,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 49 | 95 | 133 | 245 | 379 | 665 | 931 | 1,895 | 2,653 | 4,655 | 7,201 | 13,265 | 18,571 | 36,005 | 50,407 | 92,855 | 252,035 | 352,849 | 1,764,245 |
| -1 | -5 | -7 | -19 | -35 | -49 | -95 | -133 | -245 | -379 | -665 | -931 | -1,895 | -2,653 | -4,655 | -7,201 | -13,265 | -18,571 | -36,005 | -50,407 | -92,855 | -252,035 | -352,849 | -1,764,245 |
