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 770,732,557, 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 | 770,732,557 | |
| -1 | -770,732,557 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 770,732,557.
Example:
1 x 770,732,557 = 770,732,557
and
-1 x -770,732,557 = 770,732,557
Notice both answers equal 770,732,557
With that explanation out of the way, let's continue. Next, we take the number 770,732,557 and divide it by 2:
770,732,557 ÷ 2 = 385,366,278.5
If the quotient is a whole number, then 2 and 385,366,278.5 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 | 770,732,557 | |
| -1 | -770,732,557 |
Now, we try dividing 770,732,557 by 3:
770,732,557 ÷ 3 = 256,910,852.3333
If the quotient is a whole number, then 3 and 256,910,852.3333 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 | 770,732,557 | |
| -1 | -770,732,557 |
Let's try dividing by 4:
770,732,557 ÷ 4 = 192,683,139.25
If the quotient is a whole number, then 4 and 192,683,139.25 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 | 770,732,557 | |
| -1 | 770,732,557 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 469 | 769 | 2,137 | 5,383 | 14,959 | 51,523 | 143,179 | 360,661 | 1,002,253 | 1,643,353 | 11,503,471 | 110,104,651 | 770,732,557 |
| -1 | -7 | -67 | -469 | -769 | -2,137 | -5,383 | -14,959 | -51,523 | -143,179 | -360,661 | -1,002,253 | -1,643,353 | -11,503,471 | -110,104,651 | -770,732,557 |
