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 1,542,325, 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 | 1,542,325 | |
| -1 | -1,542,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,542,325.
Example:
1 x 1,542,325 = 1,542,325
and
-1 x -1,542,325 = 1,542,325
Notice both answers equal 1,542,325
With that explanation out of the way, let's continue. Next, we take the number 1,542,325 and divide it by 2:
1,542,325 ÷ 2 = 771,162.5
If the quotient is a whole number, then 2 and 771,162.5 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 | 1,542,325 | |
| -1 | -1,542,325 |
Now, we try dividing 1,542,325 by 3:
1,542,325 ÷ 3 = 514,108.3333
If the quotient is a whole number, then 3 and 514,108.3333 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 | 1,542,325 | |
| -1 | -1,542,325 |
Let's try dividing by 4:
1,542,325 ÷ 4 = 385,581.25
If the quotient is a whole number, then 4 and 385,581.25 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 | 1,542,325 | |
| -1 | 1,542,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 19 | 25 | 85 | 95 | 191 | 323 | 425 | 475 | 955 | 1,615 | 3,247 | 3,629 | 4,775 | 8,075 | 16,235 | 18,145 | 61,693 | 81,175 | 90,725 | 308,465 | 1,542,325 |
| -1 | -5 | -17 | -19 | -25 | -85 | -95 | -191 | -323 | -425 | -475 | -955 | -1,615 | -3,247 | -3,629 | -4,775 | -8,075 | -16,235 | -18,145 | -61,693 | -81,175 | -90,725 | -308,465 | -1,542,325 |
