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 764,376,565, 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 | 764,376,565 | |
| -1 | -764,376,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 764,376,565.
Example:
1 x 764,376,565 = 764,376,565
and
-1 x -764,376,565 = 764,376,565
Notice both answers equal 764,376,565
With that explanation out of the way, let's continue. Next, we take the number 764,376,565 and divide it by 2:
764,376,565 ÷ 2 = 382,188,282.5
If the quotient is a whole number, then 2 and 382,188,282.5 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 | 764,376,565 | |
| -1 | -764,376,565 |
Now, we try dividing 764,376,565 by 3:
764,376,565 ÷ 3 = 254,792,188.3333
If the quotient is a whole number, then 3 and 254,792,188.3333 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 | 764,376,565 | |
| -1 | -764,376,565 |
Let's try dividing by 4:
764,376,565 ÷ 4 = 191,094,141.25
If the quotient is a whole number, then 4 and 191,094,141.25 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 | 764,376,565 | |
| -1 | 764,376,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 295 | 443 | 2,215 | 5,849 | 26,137 | 29,245 | 130,685 | 345,091 | 1,725,455 | 2,591,107 | 12,955,535 | 152,875,313 | 764,376,565 |
| -1 | -5 | -59 | -295 | -443 | -2,215 | -5,849 | -26,137 | -29,245 | -130,685 | -345,091 | -1,725,455 | -2,591,107 | -12,955,535 | -152,875,313 | -764,376,565 |
