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 1,530,529, 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 | 1,530,529 | |
| -1 | -1,530,529 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,530,529.
Example:
1 x 1,530,529 = 1,530,529
and
-1 x -1,530,529 = 1,530,529
Notice both answers equal 1,530,529
With that explanation out of the way, let's continue. Next, we take the number 1,530,529 and divide it by 2:
1,530,529 ÷ 2 = 765,264.5
If the quotient is a whole number, then 2 and 765,264.5 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 | 1,530,529 | |
| -1 | -1,530,529 |
Now, we try dividing 1,530,529 by 3:
1,530,529 ÷ 3 = 510,176.3333
If the quotient is a whole number, then 3 and 510,176.3333 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 | 1,530,529 | |
| -1 | -1,530,529 |
Let's try dividing by 4:
1,530,529 ÷ 4 = 382,632.25
If the quotient is a whole number, then 4 and 382,632.25 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 | 1,530,529 | |
| -1 | 1,530,529 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 121 | 139 | 143 | 847 | 973 | 1,001 | 1,529 | 1,573 | 1,807 | 10,703 | 11,011 | 12,649 | 16,819 | 19,877 | 117,733 | 139,139 | 218,647 | 1,530,529 |
| -1 | -7 | -11 | -13 | -77 | -91 | -121 | -139 | -143 | -847 | -973 | -1,001 | -1,529 | -1,573 | -1,807 | -10,703 | -11,011 | -12,649 | -16,819 | -19,877 | -117,733 | -139,139 | -218,647 | -1,530,529 |
