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 1,862,015, 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 | 1,862,015 | |
| -1 | -1,862,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,862,015.
Example:
1 x 1,862,015 = 1,862,015
and
-1 x -1,862,015 = 1,862,015
Notice both answers equal 1,862,015
With that explanation out of the way, let's continue. Next, we take the number 1,862,015 and divide it by 2:
1,862,015 ÷ 2 = 931,007.5
If the quotient is a whole number, then 2 and 931,007.5 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 | 1,862,015 | |
| -1 | -1,862,015 |
Now, we try dividing 1,862,015 by 3:
1,862,015 ÷ 3 = 620,671.6667
If the quotient is a whole number, then 3 and 620,671.6667 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 | 1,862,015 | |
| -1 | -1,862,015 |
Let's try dividing by 4:
1,862,015 ÷ 4 = 465,503.75
If the quotient is a whole number, then 4 and 465,503.75 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 | 1,862,015 | |
| -1 | 1,862,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 41 | 155 | 205 | 293 | 1,271 | 1,465 | 6,355 | 9,083 | 12,013 | 45,415 | 60,065 | 372,403 | 1,862,015 |
| -1 | -5 | -31 | -41 | -155 | -205 | -293 | -1,271 | -1,465 | -6,355 | -9,083 | -12,013 | -45,415 | -60,065 | -372,403 | -1,862,015 |
