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 316,003,025, 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 | 316,003,025 | |
| -1 | -316,003,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 316,003,025.
Example:
1 x 316,003,025 = 316,003,025
and
-1 x -316,003,025 = 316,003,025
Notice both answers equal 316,003,025
With that explanation out of the way, let's continue. Next, we take the number 316,003,025 and divide it by 2:
316,003,025 ÷ 2 = 158,001,512.5
If the quotient is a whole number, then 2 and 158,001,512.5 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 | 316,003,025 | |
| -1 | -316,003,025 |
Now, we try dividing 316,003,025 by 3:
316,003,025 ÷ 3 = 105,334,341.6667
If the quotient is a whole number, then 3 and 105,334,341.6667 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 | 316,003,025 | |
| -1 | -316,003,025 |
Let's try dividing by 4:
316,003,025 ÷ 4 = 79,000,756.25
If the quotient is a whole number, then 4 and 79,000,756.25 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 | 316,003,025 | |
| -1 | 316,003,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 325 | 653 | 1,489 | 3,265 | 7,445 | 8,489 | 16,325 | 19,357 | 37,225 | 42,445 | 96,785 | 212,225 | 483,925 | 972,317 | 4,861,585 | 12,640,121 | 24,307,925 | 63,200,605 | 316,003,025 |
| -1 | -5 | -13 | -25 | -65 | -325 | -653 | -1,489 | -3,265 | -7,445 | -8,489 | -16,325 | -19,357 | -37,225 | -42,445 | -96,785 | -212,225 | -483,925 | -972,317 | -4,861,585 | -12,640,121 | -24,307,925 | -63,200,605 | -316,003,025 |
