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 783,265, 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 | 783,265 | |
| -1 | -783,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 783,265.
Example:
1 x 783,265 = 783,265
and
-1 x -783,265 = 783,265
Notice both answers equal 783,265
With that explanation out of the way, let's continue. Next, we take the number 783,265 and divide it by 2:
783,265 ÷ 2 = 391,632.5
If the quotient is a whole number, then 2 and 391,632.5 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 | 783,265 | |
| -1 | -783,265 |
Now, we try dividing 783,265 by 3:
783,265 ÷ 3 = 261,088.3333
If the quotient is a whole number, then 3 and 261,088.3333 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 | 783,265 | |
| -1 | -783,265 |
Let's try dividing by 4:
783,265 ÷ 4 = 195,816.25
If the quotient is a whole number, then 4 and 195,816.25 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 | 783,265 | |
| -1 | 783,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 49 | 115 | 139 | 161 | 245 | 695 | 805 | 973 | 1,127 | 3,197 | 4,865 | 5,635 | 6,811 | 15,985 | 22,379 | 34,055 | 111,895 | 156,653 | 783,265 |
| -1 | -5 | -7 | -23 | -35 | -49 | -115 | -139 | -161 | -245 | -695 | -805 | -973 | -1,127 | -3,197 | -4,865 | -5,635 | -6,811 | -15,985 | -22,379 | -34,055 | -111,895 | -156,653 | -783,265 |
