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 782,275, 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 | 782,275 | |
| -1 | -782,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 782,275.
Example:
1 x 782,275 = 782,275
and
-1 x -782,275 = 782,275
Notice both answers equal 782,275
With that explanation out of the way, let's continue. Next, we take the number 782,275 and divide it by 2:
782,275 ÷ 2 = 391,137.5
If the quotient is a whole number, then 2 and 391,137.5 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 | 782,275 | |
| -1 | -782,275 |
Now, we try dividing 782,275 by 3:
782,275 ÷ 3 = 260,758.3333
If the quotient is a whole number, then 3 and 260,758.3333 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 | 782,275 | |
| -1 | -782,275 |
Let's try dividing by 4:
782,275 ÷ 4 = 195,568.75
If the quotient is a whole number, then 4 and 195,568.75 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 | 782,275 | |
| -1 | 782,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 29 | 65 | 83 | 145 | 325 | 377 | 415 | 725 | 1,079 | 1,885 | 2,075 | 2,407 | 5,395 | 9,425 | 12,035 | 26,975 | 31,291 | 60,175 | 156,455 | 782,275 |
| -1 | -5 | -13 | -25 | -29 | -65 | -83 | -145 | -325 | -377 | -415 | -725 | -1,079 | -1,885 | -2,075 | -2,407 | -5,395 | -9,425 | -12,035 | -26,975 | -31,291 | -60,175 | -156,455 | -782,275 |
