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 1,492,543, 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 | 1,492,543 | |
| -1 | -1,492,543 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,492,543.
Example:
1 x 1,492,543 = 1,492,543
and
-1 x -1,492,543 = 1,492,543
Notice both answers equal 1,492,543
With that explanation out of the way, let's continue. Next, we take the number 1,492,543 and divide it by 2:
1,492,543 ÷ 2 = 746,271.5
If the quotient is a whole number, then 2 and 746,271.5 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 | 1,492,543 | |
| -1 | -1,492,543 |
Now, we try dividing 1,492,543 by 3:
1,492,543 ÷ 3 = 497,514.3333
If the quotient is a whole number, then 3 and 497,514.3333 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 | 1,492,543 | |
| -1 | -1,492,543 |
Let's try dividing by 4:
1,492,543 ÷ 4 = 373,135.75
If the quotient is a whole number, then 4 and 373,135.75 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 | 1,492,543 | |
| -1 | 1,492,543 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 37 | 107 | 377 | 481 | 1,073 | 1,391 | 3,103 | 3,959 | 13,949 | 40,339 | 51,467 | 114,811 | 1,492,543 |
| -1 | -13 | -29 | -37 | -107 | -377 | -481 | -1,073 | -1,391 | -3,103 | -3,959 | -13,949 | -40,339 | -51,467 | -114,811 | -1,492,543 |
