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 746,731,765, 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 | 746,731,765 | |
| -1 | -746,731,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 746,731,765.
Example:
1 x 746,731,765 = 746,731,765
and
-1 x -746,731,765 = 746,731,765
Notice both answers equal 746,731,765
With that explanation out of the way, let's continue. Next, we take the number 746,731,765 and divide it by 2:
746,731,765 ÷ 2 = 373,365,882.5
If the quotient is a whole number, then 2 and 373,365,882.5 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 | 746,731,765 | |
| -1 | -746,731,765 |
Now, we try dividing 746,731,765 by 3:
746,731,765 ÷ 3 = 248,910,588.3333
If the quotient is a whole number, then 3 and 248,910,588.3333 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 | 746,731,765 | |
| -1 | -746,731,765 |
Let's try dividing by 4:
746,731,765 ÷ 4 = 186,682,941.25
If the quotient is a whole number, then 4 and 186,682,941.25 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 | 746,731,765 | |
| -1 | 746,731,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 43 | 65 | 215 | 559 | 2,795 | 267,167 | 1,335,835 | 3,473,171 | 11,488,181 | 17,365,855 | 57,440,905 | 149,346,353 | 746,731,765 |
| -1 | -5 | -13 | -43 | -65 | -215 | -559 | -2,795 | -267,167 | -1,335,835 | -3,473,171 | -11,488,181 | -17,365,855 | -57,440,905 | -149,346,353 | -746,731,765 |
