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 1,903,475, 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 | 1,903,475 | |
| -1 | -1,903,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,903,475.
Example:
1 x 1,903,475 = 1,903,475
and
-1 x -1,903,475 = 1,903,475
Notice both answers equal 1,903,475
With that explanation out of the way, let's continue. Next, we take the number 1,903,475 and divide it by 2:
1,903,475 ÷ 2 = 951,737.5
If the quotient is a whole number, then 2 and 951,737.5 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 | 1,903,475 | |
| -1 | -1,903,475 |
Now, we try dividing 1,903,475 by 3:
1,903,475 ÷ 3 = 634,491.6667
If the quotient is a whole number, then 3 and 634,491.6667 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 | 1,903,475 | |
| -1 | -1,903,475 |
Let's try dividing by 4:
1,903,475 ÷ 4 = 475,868.75
If the quotient is a whole number, then 4 and 475,868.75 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 | 1,903,475 | |
| -1 | 1,903,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 73 | 149 | 175 | 365 | 511 | 745 | 1,043 | 1,825 | 2,555 | 3,725 | 5,215 | 10,877 | 12,775 | 26,075 | 54,385 | 76,139 | 271,925 | 380,695 | 1,903,475 |
| -1 | -5 | -7 | -25 | -35 | -73 | -149 | -175 | -365 | -511 | -745 | -1,043 | -1,825 | -2,555 | -3,725 | -5,215 | -10,877 | -12,775 | -26,075 | -54,385 | -76,139 | -271,925 | -380,695 | -1,903,475 |
