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 741,237,077, 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 | 741,237,077 | |
| -1 | -741,237,077 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 741,237,077.
Example:
1 x 741,237,077 = 741,237,077
and
-1 x -741,237,077 = 741,237,077
Notice both answers equal 741,237,077
With that explanation out of the way, let's continue. Next, we take the number 741,237,077 and divide it by 2:
741,237,077 ÷ 2 = 370,618,538.5
If the quotient is a whole number, then 2 and 370,618,538.5 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 | 741,237,077 | |
| -1 | -741,237,077 |
Now, we try dividing 741,237,077 by 3:
741,237,077 ÷ 3 = 247,079,025.6667
If the quotient is a whole number, then 3 and 247,079,025.6667 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 | 741,237,077 | |
| -1 | -741,237,077 |
Let's try dividing by 4:
741,237,077 ÷ 4 = 185,309,269.25
If the quotient is a whole number, then 4 and 185,309,269.25 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 | 741,237,077 | |
| -1 | 741,237,077 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 23 | 119 | 161 | 391 | 2,737 | 270,821 | 1,895,747 | 4,603,957 | 6,228,883 | 32,227,699 | 43,602,181 | 105,891,011 | 741,237,077 |
| -1 | -7 | -17 | -23 | -119 | -161 | -391 | -2,737 | -270,821 | -1,895,747 | -4,603,957 | -6,228,883 | -32,227,699 | -43,602,181 | -105,891,011 | -741,237,077 |
