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 772,145, 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 | 772,145 | |
| -1 | -772,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 772,145.
Example:
1 x 772,145 = 772,145
and
-1 x -772,145 = 772,145
Notice both answers equal 772,145
With that explanation out of the way, let's continue. Next, we take the number 772,145 and divide it by 2:
772,145 ÷ 2 = 386,072.5
If the quotient is a whole number, then 2 and 386,072.5 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 | 772,145 | |
| -1 | -772,145 |
Now, we try dividing 772,145 by 3:
772,145 ÷ 3 = 257,381.6667
If the quotient is a whole number, then 3 and 257,381.6667 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 | 772,145 | |
| -1 | -772,145 |
Let's try dividing by 4:
772,145 ÷ 4 = 193,036.25
If the quotient is a whole number, then 4 and 193,036.25 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 | 772,145 | |
| -1 | 772,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 101 | 139 | 505 | 695 | 1,111 | 1,529 | 5,555 | 7,645 | 14,039 | 70,195 | 154,429 | 772,145 |
| -1 | -5 | -11 | -55 | -101 | -139 | -505 | -695 | -1,111 | -1,529 | -5,555 | -7,645 | -14,039 | -70,195 | -154,429 | -772,145 |
