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 764,750,567, 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 | 764,750,567 | |
| -1 | -764,750,567 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 764,750,567.
Example:
1 x 764,750,567 = 764,750,567
and
-1 x -764,750,567 = 764,750,567
Notice both answers equal 764,750,567
With that explanation out of the way, let's continue. Next, we take the number 764,750,567 and divide it by 2:
764,750,567 ÷ 2 = 382,375,283.5
If the quotient is a whole number, then 2 and 382,375,283.5 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 | 764,750,567 | |
| -1 | -764,750,567 |
Now, we try dividing 764,750,567 by 3:
764,750,567 ÷ 3 = 254,916,855.6667
If the quotient is a whole number, then 3 and 254,916,855.6667 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 | 764,750,567 | |
| -1 | -764,750,567 |
Let's try dividing by 4:
764,750,567 ÷ 4 = 191,187,641.75
If the quotient is a whole number, then 4 and 191,187,641.75 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 | 764,750,567 | |
| -1 | 764,750,567 |
If you did it right, you will end up with this table:
| 1 | 7 | 89 | 541 | 623 | 2,269 | 3,787 | 15,883 | 48,149 | 201,941 | 337,043 | 1,227,529 | 1,413,587 | 8,592,703 | 109,250,081 | 764,750,567 |
| -1 | -7 | -89 | -541 | -623 | -2,269 | -3,787 | -15,883 | -48,149 | -201,941 | -337,043 | -1,227,529 | -1,413,587 | -8,592,703 | -109,250,081 | -764,750,567 |
