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 745,532,609, 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 | 745,532,609 | |
| -1 | -745,532,609 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 745,532,609.
Example:
1 x 745,532,609 = 745,532,609
and
-1 x -745,532,609 = 745,532,609
Notice both answers equal 745,532,609
With that explanation out of the way, let's continue. Next, we take the number 745,532,609 and divide it by 2:
745,532,609 ÷ 2 = 372,766,304.5
If the quotient is a whole number, then 2 and 372,766,304.5 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 | 745,532,609 | |
| -1 | -745,532,609 |
Now, we try dividing 745,532,609 by 3:
745,532,609 ÷ 3 = 248,510,869.6667
If the quotient is a whole number, then 3 and 248,510,869.6667 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 | 745,532,609 | |
| -1 | -745,532,609 |
Let's try dividing by 4:
745,532,609 ÷ 4 = 186,383,152.25
If the quotient is a whole number, then 4 and 186,383,152.25 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 | 745,532,609 | |
| -1 | 745,532,609 |
If you did it right, you will end up with this table:
| 1 | 29 | 31 | 53 | 899 | 1,537 | 1,643 | 15,647 | 47,647 | 453,763 | 485,057 | 829,291 | 14,066,653 | 24,049,439 | 25,708,021 | 745,532,609 |
| -1 | -29 | -31 | -53 | -899 | -1,537 | -1,643 | -15,647 | -47,647 | -453,763 | -485,057 | -829,291 | -14,066,653 | -24,049,439 | -25,708,021 | -745,532,609 |
