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 1,252,075, 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 | 1,252,075 | |
| -1 | -1,252,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,252,075.
Example:
1 x 1,252,075 = 1,252,075
and
-1 x -1,252,075 = 1,252,075
Notice both answers equal 1,252,075
With that explanation out of the way, let's continue. Next, we take the number 1,252,075 and divide it by 2:
1,252,075 ÷ 2 = 626,037.5
If the quotient is a whole number, then 2 and 626,037.5 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 | 1,252,075 | |
| -1 | -1,252,075 |
Now, we try dividing 1,252,075 by 3:
1,252,075 ÷ 3 = 417,358.3333
If the quotient is a whole number, then 3 and 417,358.3333 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 | 1,252,075 | |
| -1 | -1,252,075 |
Let's try dividing by 4:
1,252,075 ÷ 4 = 313,018.75
If the quotient is a whole number, then 4 and 313,018.75 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 | 1,252,075 | |
| -1 | 1,252,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 29 | 55 | 145 | 157 | 275 | 319 | 725 | 785 | 1,595 | 1,727 | 3,925 | 4,553 | 7,975 | 8,635 | 22,765 | 43,175 | 50,083 | 113,825 | 250,415 | 1,252,075 |
| -1 | -5 | -11 | -25 | -29 | -55 | -145 | -157 | -275 | -319 | -725 | -785 | -1,595 | -1,727 | -3,925 | -4,553 | -7,975 | -8,635 | -22,765 | -43,175 | -50,083 | -113,825 | -250,415 | -1,252,075 |
