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 741,075,115, 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 | 741,075,115 | |
| -1 | -741,075,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 741,075,115.
Example:
1 x 741,075,115 = 741,075,115
and
-1 x -741,075,115 = 741,075,115
Notice both answers equal 741,075,115
With that explanation out of the way, let's continue. Next, we take the number 741,075,115 and divide it by 2:
741,075,115 ÷ 2 = 370,537,557.5
If the quotient is a whole number, then 2 and 370,537,557.5 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 | 741,075,115 | |
| -1 | -741,075,115 |
Now, we try dividing 741,075,115 by 3:
741,075,115 ÷ 3 = 247,025,038.3333
If the quotient is a whole number, then 3 and 247,025,038.3333 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 | 741,075,115 | |
| -1 | -741,075,115 |
Let's try dividing by 4:
741,075,115 ÷ 4 = 185,268,778.75
If the quotient is a whole number, then 4 and 185,268,778.75 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 | 741,075,115 | |
| -1 | 741,075,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 43 | 55 | 215 | 473 | 2,365 | 313,351 | 1,566,755 | 3,446,861 | 13,474,093 | 17,234,305 | 67,370,465 | 148,215,023 | 741,075,115 |
| -1 | -5 | -11 | -43 | -55 | -215 | -473 | -2,365 | -313,351 | -1,566,755 | -3,446,861 | -13,474,093 | -17,234,305 | -67,370,465 | -148,215,023 | -741,075,115 |
