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 320,213,425, 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 | 320,213,425 | |
| -1 | -320,213,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 320,213,425.
Example:
1 x 320,213,425 = 320,213,425
and
-1 x -320,213,425 = 320,213,425
Notice both answers equal 320,213,425
With that explanation out of the way, let's continue. Next, we take the number 320,213,425 and divide it by 2:
320,213,425 ÷ 2 = 160,106,712.5
If the quotient is a whole number, then 2 and 160,106,712.5 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 | 320,213,425 | |
| -1 | -320,213,425 |
Now, we try dividing 320,213,425 by 3:
320,213,425 ÷ 3 = 106,737,808.3333
If the quotient is a whole number, then 3 and 106,737,808.3333 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 | 320,213,425 | |
| -1 | -320,213,425 |
Let's try dividing by 4:
320,213,425 ÷ 4 = 80,053,356.25
If the quotient is a whole number, then 4 and 80,053,356.25 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 | 320,213,425 | |
| -1 | 320,213,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 1,051 | 1,741 | 5,255 | 7,357 | 8,705 | 12,187 | 26,275 | 36,785 | 43,525 | 60,935 | 183,925 | 304,675 | 1,829,791 | 9,148,955 | 12,808,537 | 45,744,775 | 64,042,685 | 320,213,425 |
| -1 | -5 | -7 | -25 | -35 | -175 | -1,051 | -1,741 | -5,255 | -7,357 | -8,705 | -12,187 | -26,275 | -36,785 | -43,525 | -60,935 | -183,925 | -304,675 | -1,829,791 | -9,148,955 | -12,808,537 | -45,744,775 | -64,042,685 | -320,213,425 |
