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 1,666,525, 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 | 1,666,525 | |
| -1 | -1,666,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,666,525.
Example:
1 x 1,666,525 = 1,666,525
and
-1 x -1,666,525 = 1,666,525
Notice both answers equal 1,666,525
With that explanation out of the way, let's continue. Next, we take the number 1,666,525 and divide it by 2:
1,666,525 ÷ 2 = 833,262.5
If the quotient is a whole number, then 2 and 833,262.5 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 | 1,666,525 | |
| -1 | -1,666,525 |
Now, we try dividing 1,666,525 by 3:
1,666,525 ÷ 3 = 555,508.3333
If the quotient is a whole number, then 3 and 555,508.3333 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 | 1,666,525 | |
| -1 | -1,666,525 |
Let's try dividing by 4:
1,666,525 ÷ 4 = 416,631.25
If the quotient is a whole number, then 4 and 416,631.25 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 | 1,666,525 | |
| -1 | 1,666,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 89 | 107 | 175 | 445 | 535 | 623 | 749 | 2,225 | 2,675 | 3,115 | 3,745 | 9,523 | 15,575 | 18,725 | 47,615 | 66,661 | 238,075 | 333,305 | 1,666,525 |
| -1 | -5 | -7 | -25 | -35 | -89 | -107 | -175 | -445 | -535 | -623 | -749 | -2,225 | -2,675 | -3,115 | -3,745 | -9,523 | -15,575 | -18,725 | -47,615 | -66,661 | -238,075 | -333,305 | -1,666,525 |
