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 769,223, 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 | 769,223 | |
| -1 | -769,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 769,223.
Example:
1 x 769,223 = 769,223
and
-1 x -769,223 = 769,223
Notice both answers equal 769,223
With that explanation out of the way, let's continue. Next, we take the number 769,223 and divide it by 2:
769,223 ÷ 2 = 384,611.5
If the quotient is a whole number, then 2 and 384,611.5 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 | 769,223 | |
| -1 | -769,223 |
Now, we try dividing 769,223 by 3:
769,223 ÷ 3 = 256,407.6667
If the quotient is a whole number, then 3 and 256,407.6667 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 | 769,223 | |
| -1 | -769,223 |
Let's try dividing by 4:
769,223 ÷ 4 = 192,305.75
If the quotient is a whole number, then 4 and 192,305.75 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 | 769,223 | |
| -1 | 769,223 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 79 | 91 | 107 | 553 | 749 | 1,027 | 1,391 | 7,189 | 8,453 | 9,737 | 59,171 | 109,889 | 769,223 |
| -1 | -7 | -13 | -79 | -91 | -107 | -553 | -749 | -1,027 | -1,391 | -7,189 | -8,453 | -9,737 | -59,171 | -109,889 | -769,223 |
