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 1,867,075, 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 | 1,867,075 | |
| -1 | -1,867,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,867,075.
Example:
1 x 1,867,075 = 1,867,075
and
-1 x -1,867,075 = 1,867,075
Notice both answers equal 1,867,075
With that explanation out of the way, let's continue. Next, we take the number 1,867,075 and divide it by 2:
1,867,075 ÷ 2 = 933,537.5
If the quotient is a whole number, then 2 and 933,537.5 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 | 1,867,075 | |
| -1 | -1,867,075 |
Now, we try dividing 1,867,075 by 3:
1,867,075 ÷ 3 = 622,358.3333
If the quotient is a whole number, then 3 and 622,358.3333 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 | 1,867,075 | |
| -1 | -1,867,075 |
Let's try dividing by 4:
1,867,075 ÷ 4 = 466,768.75
If the quotient is a whole number, then 4 and 466,768.75 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 | 1,867,075 | |
| -1 | 1,867,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 47 | 175 | 227 | 235 | 329 | 1,135 | 1,175 | 1,589 | 1,645 | 5,675 | 7,945 | 8,225 | 10,669 | 39,725 | 53,345 | 74,683 | 266,725 | 373,415 | 1,867,075 |
| -1 | -5 | -7 | -25 | -35 | -47 | -175 | -227 | -235 | -329 | -1,135 | -1,175 | -1,589 | -1,645 | -5,675 | -7,945 | -8,225 | -10,669 | -39,725 | -53,345 | -74,683 | -266,725 | -373,415 | -1,867,075 |
