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 745,333,625, 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 | 745,333,625 | |
| -1 | -745,333,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 745,333,625.
Example:
1 x 745,333,625 = 745,333,625
and
-1 x -745,333,625 = 745,333,625
Notice both answers equal 745,333,625
With that explanation out of the way, let's continue. Next, we take the number 745,333,625 and divide it by 2:
745,333,625 ÷ 2 = 372,666,812.5
If the quotient is a whole number, then 2 and 372,666,812.5 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 | 745,333,625 | |
| -1 | -745,333,625 |
Now, we try dividing 745,333,625 by 3:
745,333,625 ÷ 3 = 248,444,541.6667
If the quotient is a whole number, then 3 and 248,444,541.6667 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 | 745,333,625 | |
| -1 | -745,333,625 |
Let's try dividing by 4:
745,333,625 ÷ 4 = 186,333,406.25
If the quotient is a whole number, then 4 and 186,333,406.25 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 | 745,333,625 | |
| -1 | 745,333,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 179 | 895 | 4,475 | 22,375 | 33,311 | 166,555 | 832,775 | 4,163,875 | 5,962,669 | 29,813,345 | 149,066,725 | 745,333,625 |
| -1 | -5 | -25 | -125 | -179 | -895 | -4,475 | -22,375 | -33,311 | -166,555 | -832,775 | -4,163,875 | -5,962,669 | -29,813,345 | -149,066,725 | -745,333,625 |
