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 1,051,435, 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 | 1,051,435 | |
| -1 | -1,051,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,051,435.
Example:
1 x 1,051,435 = 1,051,435
and
-1 x -1,051,435 = 1,051,435
Notice both answers equal 1,051,435
With that explanation out of the way, let's continue. Next, we take the number 1,051,435 and divide it by 2:
1,051,435 ÷ 2 = 525,717.5
If the quotient is a whole number, then 2 and 525,717.5 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 | 1,051,435 | |
| -1 | -1,051,435 |
Now, we try dividing 1,051,435 by 3:
1,051,435 ÷ 3 = 350,478.3333
If the quotient is a whole number, then 3 and 350,478.3333 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 | 1,051,435 | |
| -1 | -1,051,435 |
Let's try dividing by 4:
1,051,435 ÷ 4 = 262,858.75
If the quotient is a whole number, then 4 and 262,858.75 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 | 1,051,435 | |
| -1 | 1,051,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 2,731 | 13,655 | 19,117 | 30,041 | 95,585 | 150,205 | 210,287 | 1,051,435 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -2,731 | -13,655 | -19,117 | -30,041 | -95,585 | -150,205 | -210,287 | -1,051,435 |
