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 1,837,585, 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 | 1,837,585 | |
| -1 | -1,837,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,837,585.
Example:
1 x 1,837,585 = 1,837,585
and
-1 x -1,837,585 = 1,837,585
Notice both answers equal 1,837,585
With that explanation out of the way, let's continue. Next, we take the number 1,837,585 and divide it by 2:
1,837,585 ÷ 2 = 918,792.5
If the quotient is a whole number, then 2 and 918,792.5 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 | 1,837,585 | |
| -1 | -1,837,585 |
Now, we try dividing 1,837,585 by 3:
1,837,585 ÷ 3 = 612,528.3333
If the quotient is a whole number, then 3 and 612,528.3333 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 | 1,837,585 | |
| -1 | -1,837,585 |
Let's try dividing by 4:
1,837,585 ÷ 4 = 459,396.25
If the quotient is a whole number, then 4 and 459,396.25 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 | 1,837,585 | |
| -1 | 1,837,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 23 | 29 | 95 | 115 | 145 | 437 | 551 | 667 | 841 | 2,185 | 2,755 | 3,335 | 4,205 | 12,673 | 15,979 | 19,343 | 63,365 | 79,895 | 96,715 | 367,517 | 1,837,585 |
| -1 | -5 | -19 | -23 | -29 | -95 | -115 | -145 | -437 | -551 | -667 | -841 | -2,185 | -2,755 | -3,335 | -4,205 | -12,673 | -15,979 | -19,343 | -63,365 | -79,895 | -96,715 | -367,517 | -1,837,585 |
