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 1,869,133, 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 | 1,869,133 | |
| -1 | -1,869,133 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,869,133.
Example:
1 x 1,869,133 = 1,869,133
and
-1 x -1,869,133 = 1,869,133
Notice both answers equal 1,869,133
With that explanation out of the way, let's continue. Next, we take the number 1,869,133 and divide it by 2:
1,869,133 ÷ 2 = 934,566.5
If the quotient is a whole number, then 2 and 934,566.5 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 | 1,869,133 | |
| -1 | -1,869,133 |
Now, we try dividing 1,869,133 by 3:
1,869,133 ÷ 3 = 623,044.3333
If the quotient is a whole number, then 3 and 623,044.3333 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 | 1,869,133 | |
| -1 | -1,869,133 |
Let's try dividing by 4:
1,869,133 ÷ 4 = 467,283.25
If the quotient is a whole number, then 4 and 467,283.25 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 | 1,869,133 | |
| -1 | 1,869,133 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 113 | 119 | 139 | 791 | 973 | 1,921 | 2,363 | 13,447 | 15,707 | 16,541 | 109,949 | 267,019 | 1,869,133 |
| -1 | -7 | -17 | -113 | -119 | -139 | -791 | -973 | -1,921 | -2,363 | -13,447 | -15,707 | -16,541 | -109,949 | -267,019 | -1,869,133 |
