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 764,281,343, 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 | 764,281,343 | |
| -1 | -764,281,343 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 764,281,343.
Example:
1 x 764,281,343 = 764,281,343
and
-1 x -764,281,343 = 764,281,343
Notice both answers equal 764,281,343
With that explanation out of the way, let's continue. Next, we take the number 764,281,343 and divide it by 2:
764,281,343 ÷ 2 = 382,140,671.5
If the quotient is a whole number, then 2 and 382,140,671.5 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 | 764,281,343 | |
| -1 | -764,281,343 |
Now, we try dividing 764,281,343 by 3:
764,281,343 ÷ 3 = 254,760,447.6667
If the quotient is a whole number, then 3 and 254,760,447.6667 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 | 764,281,343 | |
| -1 | -764,281,343 |
Let's try dividing by 4:
764,281,343 ÷ 4 = 191,070,335.75
If the quotient is a whole number, then 4 and 191,070,335.75 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 | 764,281,343 | |
| -1 | 764,281,343 |
If you did it right, you will end up with this table:
| 1 | 7 | 191 | 523 | 1,093 | 1,337 | 3,661 | 7,651 | 99,893 | 208,763 | 571,639 | 699,251 | 1,461,341 | 4,001,473 | 109,183,049 | 764,281,343 |
| -1 | -7 | -191 | -523 | -1,093 | -1,337 | -3,661 | -7,651 | -99,893 | -208,763 | -571,639 | -699,251 | -1,461,341 | -4,001,473 | -109,183,049 | -764,281,343 |
