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 1,427,915, 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 | 1,427,915 | |
| -1 | -1,427,915 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,427,915.
Example:
1 x 1,427,915 = 1,427,915
and
-1 x -1,427,915 = 1,427,915
Notice both answers equal 1,427,915
With that explanation out of the way, let's continue. Next, we take the number 1,427,915 and divide it by 2:
1,427,915 ÷ 2 = 713,957.5
If the quotient is a whole number, then 2 and 713,957.5 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 | 1,427,915 | |
| -1 | -1,427,915 |
Now, we try dividing 1,427,915 by 3:
1,427,915 ÷ 3 = 475,971.6667
If the quotient is a whole number, then 3 and 475,971.6667 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 | 1,427,915 | |
| -1 | -1,427,915 |
Let's try dividing by 4:
1,427,915 ÷ 4 = 356,978.75
If the quotient is a whole number, then 4 and 356,978.75 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 | 1,427,915 | |
| -1 | 1,427,915 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 107 | 157 | 535 | 785 | 1,819 | 2,669 | 9,095 | 13,345 | 16,799 | 83,995 | 285,583 | 1,427,915 |
| -1 | -5 | -17 | -85 | -107 | -157 | -535 | -785 | -1,819 | -2,669 | -9,095 | -13,345 | -16,799 | -83,995 | -285,583 | -1,427,915 |
