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 1,870,375, 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 | 1,870,375 | |
| -1 | -1,870,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,870,375.
Example:
1 x 1,870,375 = 1,870,375
and
-1 x -1,870,375 = 1,870,375
Notice both answers equal 1,870,375
With that explanation out of the way, let's continue. Next, we take the number 1,870,375 and divide it by 2:
1,870,375 ÷ 2 = 935,187.5
If the quotient is a whole number, then 2 and 935,187.5 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 | 1,870,375 | |
| -1 | -1,870,375 |
Now, we try dividing 1,870,375 by 3:
1,870,375 ÷ 3 = 623,458.3333
If the quotient is a whole number, then 3 and 623,458.3333 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 | 1,870,375 | |
| -1 | -1,870,375 |
Let's try dividing by 4:
1,870,375 ÷ 4 = 467,593.75
If the quotient is a whole number, then 4 and 467,593.75 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 | 1,870,375 | |
| -1 | 1,870,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 125 | 325 | 1,151 | 1,625 | 5,755 | 14,963 | 28,775 | 74,815 | 143,875 | 374,075 | 1,870,375 |
| -1 | -5 | -13 | -25 | -65 | -125 | -325 | -1,151 | -1,625 | -5,755 | -14,963 | -28,775 | -74,815 | -143,875 | -374,075 | -1,870,375 |
