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 832,980, 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 | 832,980 | |
| -1 | -832,980 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 832,980.
Example:
1 x 832,980 = 832,980
and
-1 x -832,980 = 832,980
Notice both answers equal 832,980
With that explanation out of the way, let's continue. Next, we take the number 832,980 and divide it by 2:
832,980 ÷ 2 = 416,490
If the quotient is a whole number, then 2 and 416,490 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 416,490 | 832,980 | |
| -1 | -2 | -416,490 | -832,980 |
Now, we try dividing 832,980 by 3:
832,980 ÷ 3 = 277,660
If the quotient is a whole number, then 3 and 277,660 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 277,660 | 416,490 | 832,980 | |
| -1 | -2 | -3 | -277,660 | -416,490 | -832,980 |
Let's try dividing by 4:
832,980 ÷ 4 = 208,245
If the quotient is a whole number, then 4 and 208,245 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 4 | 208,245 | 277,660 | 416,490 | 832,980 | |
| -1 | -2 | -3 | -4 | -208,245 | -277,660 | -416,490 | 832,980 |
If you did it right, you will end up with this table:
| 1 | 2 | 3 | 4 | 5 | 6 | 10 | 12 | 15 | 20 | 30 | 60 | 13,883 | 27,766 | 41,649 | 55,532 | 69,415 | 83,298 | 138,830 | 166,596 | 208,245 | 277,660 | 416,490 | 832,980 |
| -1 | -2 | -3 | -4 | -5 | -6 | -10 | -12 | -15 | -20 | -30 | -60 | -13,883 | -27,766 | -41,649 | -55,532 | -69,415 | -83,298 | -138,830 | -166,596 | -208,245 | -277,660 | -416,490 | -832,980 |
