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 1,975,435, 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 | 1,975,435 | |
| -1 | -1,975,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,975,435.
Example:
1 x 1,975,435 = 1,975,435
and
-1 x -1,975,435 = 1,975,435
Notice both answers equal 1,975,435
With that explanation out of the way, let's continue. Next, we take the number 1,975,435 and divide it by 2:
1,975,435 ÷ 2 = 987,717.5
If the quotient is a whole number, then 2 and 987,717.5 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 | 1,975,435 | |
| -1 | -1,975,435 |
Now, we try dividing 1,975,435 by 3:
1,975,435 ÷ 3 = 658,478.3333
If the quotient is a whole number, then 3 and 658,478.3333 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 | 1,975,435 | |
| -1 | -1,975,435 |
Let's try dividing by 4:
1,975,435 ÷ 4 = 493,858.75
If the quotient is a whole number, then 4 and 493,858.75 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 | 1,975,435 | |
| -1 | 1,975,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 49 | 55 | 77 | 245 | 385 | 539 | 733 | 2,695 | 3,665 | 5,131 | 8,063 | 25,655 | 35,917 | 40,315 | 56,441 | 179,585 | 282,205 | 395,087 | 1,975,435 |
| -1 | -5 | -7 | -11 | -35 | -49 | -55 | -77 | -245 | -385 | -539 | -733 | -2,695 | -3,665 | -5,131 | -8,063 | -25,655 | -35,917 | -40,315 | -56,441 | -179,585 | -282,205 | -395,087 | -1,975,435 |
