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 1,502,345, 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 | 1,502,345 | |
| -1 | -1,502,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,502,345.
Example:
1 x 1,502,345 = 1,502,345
and
-1 x -1,502,345 = 1,502,345
Notice both answers equal 1,502,345
With that explanation out of the way, let's continue. Next, we take the number 1,502,345 and divide it by 2:
1,502,345 ÷ 2 = 751,172.5
If the quotient is a whole number, then 2 and 751,172.5 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 | 1,502,345 | |
| -1 | -1,502,345 |
Now, we try dividing 1,502,345 by 3:
1,502,345 ÷ 3 = 500,781.6667
If the quotient is a whole number, then 3 and 500,781.6667 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 | 1,502,345 | |
| -1 | -1,502,345 |
Let's try dividing by 4:
1,502,345 ÷ 4 = 375,586.25
If the quotient is a whole number, then 4 and 375,586.25 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 | 1,502,345 | |
| -1 | 1,502,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 29 | 65 | 145 | 377 | 797 | 1,885 | 3,985 | 10,361 | 23,113 | 51,805 | 115,565 | 300,469 | 1,502,345 |
| -1 | -5 | -13 | -29 | -65 | -145 | -377 | -797 | -1,885 | -3,985 | -10,361 | -23,113 | -51,805 | -115,565 | -300,469 | -1,502,345 |
