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 1,427,755, 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 | 1,427,755 | |
| -1 | -1,427,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,427,755.
Example:
1 x 1,427,755 = 1,427,755
and
-1 x -1,427,755 = 1,427,755
Notice both answers equal 1,427,755
With that explanation out of the way, let's continue. Next, we take the number 1,427,755 and divide it by 2:
1,427,755 ÷ 2 = 713,877.5
If the quotient is a whole number, then 2 and 713,877.5 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 | 1,427,755 | |
| -1 | -1,427,755 |
Now, we try dividing 1,427,755 by 3:
1,427,755 ÷ 3 = 475,918.3333
If the quotient is a whole number, then 3 and 475,918.3333 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 | 1,427,755 | |
| -1 | -1,427,755 |
Let's try dividing by 4:
1,427,755 ÷ 4 = 356,938.75
If the quotient is a whole number, then 4 and 356,938.75 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 | 1,427,755 | |
| -1 | 1,427,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 113 | 133 | 361 | 565 | 665 | 791 | 1,805 | 2,147 | 2,527 | 3,955 | 10,735 | 12,635 | 15,029 | 40,793 | 75,145 | 203,965 | 285,551 | 1,427,755 |
| -1 | -5 | -7 | -19 | -35 | -95 | -113 | -133 | -361 | -565 | -665 | -791 | -1,805 | -2,147 | -2,527 | -3,955 | -10,735 | -12,635 | -15,029 | -40,793 | -75,145 | -203,965 | -285,551 | -1,427,755 |
