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 741,555,067, 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 | 741,555,067 | |
| -1 | -741,555,067 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 741,555,067.
Example:
1 x 741,555,067 = 741,555,067
and
-1 x -741,555,067 = 741,555,067
Notice both answers equal 741,555,067
With that explanation out of the way, let's continue. Next, we take the number 741,555,067 and divide it by 2:
741,555,067 ÷ 2 = 370,777,533.5
If the quotient is a whole number, then 2 and 370,777,533.5 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 | 741,555,067 | |
| -1 | -741,555,067 |
Now, we try dividing 741,555,067 by 3:
741,555,067 ÷ 3 = 247,185,022.3333
If the quotient is a whole number, then 3 and 247,185,022.3333 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 | 741,555,067 | |
| -1 | -741,555,067 |
Let's try dividing by 4:
741,555,067 ÷ 4 = 185,388,766.75
If the quotient is a whole number, then 4 and 185,388,766.75 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 | 741,555,067 | |
| -1 | 741,555,067 |
If you did it right, you will end up with this table:
| 1 | 11 | 79 | 359 | 869 | 2,377 | 3,949 | 26,147 | 28,361 | 187,783 | 311,971 | 853,343 | 2,065,613 | 9,386,773 | 67,414,097 | 741,555,067 |
| -1 | -11 | -79 | -359 | -869 | -2,377 | -3,949 | -26,147 | -28,361 | -187,783 | -311,971 | -853,343 | -2,065,613 | -9,386,773 | -67,414,097 | -741,555,067 |
