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 676,414,145, 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 | 676,414,145 | |
| -1 | -676,414,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 676,414,145.
Example:
1 x 676,414,145 = 676,414,145
and
-1 x -676,414,145 = 676,414,145
Notice both answers equal 676,414,145
With that explanation out of the way, let's continue. Next, we take the number 676,414,145 and divide it by 2:
676,414,145 ÷ 2 = 338,207,072.5
If the quotient is a whole number, then 2 and 338,207,072.5 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 | 676,414,145 | |
| -1 | -676,414,145 |
Now, we try dividing 676,414,145 by 3:
676,414,145 ÷ 3 = 225,471,381.6667
If the quotient is a whole number, then 3 and 225,471,381.6667 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 | 676,414,145 | |
| -1 | -676,414,145 |
Let's try dividing by 4:
676,414,145 ÷ 4 = 169,103,536.25
If the quotient is a whole number, then 4 and 169,103,536.25 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 | 676,414,145 | |
| -1 | 676,414,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 233 | 1,165 | 2,563 | 12,815 | 52,783 | 263,915 | 580,613 | 2,903,065 | 12,298,439 | 61,492,195 | 135,282,829 | 676,414,145 |
| -1 | -5 | -11 | -55 | -233 | -1,165 | -2,563 | -12,815 | -52,783 | -263,915 | -580,613 | -2,903,065 | -12,298,439 | -61,492,195 | -135,282,829 | -676,414,145 |
