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 1,430,605, 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 | 1,430,605 | |
| -1 | -1,430,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,430,605.
Example:
1 x 1,430,605 = 1,430,605
and
-1 x -1,430,605 = 1,430,605
Notice both answers equal 1,430,605
With that explanation out of the way, let's continue. Next, we take the number 1,430,605 and divide it by 2:
1,430,605 ÷ 2 = 715,302.5
If the quotient is a whole number, then 2 and 715,302.5 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 | 1,430,605 | |
| -1 | -1,430,605 |
Now, we try dividing 1,430,605 by 3:
1,430,605 ÷ 3 = 476,868.3333
If the quotient is a whole number, then 3 and 476,868.3333 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 | 1,430,605 | |
| -1 | -1,430,605 |
Let's try dividing by 4:
1,430,605 ÷ 4 = 357,651.25
If the quotient is a whole number, then 4 and 357,651.25 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 | 1,430,605 | |
| -1 | 1,430,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 37 | 55 | 95 | 185 | 209 | 407 | 703 | 1,045 | 1,369 | 2,035 | 3,515 | 6,845 | 7,733 | 15,059 | 26,011 | 38,665 | 75,295 | 130,055 | 286,121 | 1,430,605 |
| -1 | -5 | -11 | -19 | -37 | -55 | -95 | -185 | -209 | -407 | -703 | -1,045 | -1,369 | -2,035 | -3,515 | -6,845 | -7,733 | -15,059 | -26,011 | -38,665 | -75,295 | -130,055 | -286,121 | -1,430,605 |
