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 1,470,287, 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 | 1,470,287 | |
| -1 | -1,470,287 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,470,287.
Example:
1 x 1,470,287 = 1,470,287
and
-1 x -1,470,287 = 1,470,287
Notice both answers equal 1,470,287
With that explanation out of the way, let's continue. Next, we take the number 1,470,287 and divide it by 2:
1,470,287 ÷ 2 = 735,143.5
If the quotient is a whole number, then 2 and 735,143.5 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 | 1,470,287 | |
| -1 | -1,470,287 |
Now, we try dividing 1,470,287 by 3:
1,470,287 ÷ 3 = 490,095.6667
If the quotient is a whole number, then 3 and 490,095.6667 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 | 1,470,287 | |
| -1 | -1,470,287 |
Let's try dividing by 4:
1,470,287 ÷ 4 = 367,571.75
If the quotient is a whole number, then 4 and 367,571.75 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 | 1,470,287 | |
| -1 | 1,470,287 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 107 | 151 | 749 | 1,057 | 1,391 | 1,963 | 9,737 | 13,741 | 16,157 | 113,099 | 210,041 | 1,470,287 |
| -1 | -7 | -13 | -91 | -107 | -151 | -749 | -1,057 | -1,391 | -1,963 | -9,737 | -13,741 | -16,157 | -113,099 | -210,041 | -1,470,287 |
