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 777,452,627, 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 | 777,452,627 | |
| -1 | -777,452,627 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 777,452,627.
Example:
1 x 777,452,627 = 777,452,627
and
-1 x -777,452,627 = 777,452,627
Notice both answers equal 777,452,627
With that explanation out of the way, let's continue. Next, we take the number 777,452,627 and divide it by 2:
777,452,627 ÷ 2 = 388,726,313.5
If the quotient is a whole number, then 2 and 388,726,313.5 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 | 777,452,627 | |
| -1 | -777,452,627 |
Now, we try dividing 777,452,627 by 3:
777,452,627 ÷ 3 = 259,150,875.6667
If the quotient is a whole number, then 3 and 259,150,875.6667 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 | 777,452,627 | |
| -1 | -777,452,627 |
Let's try dividing by 4:
777,452,627 ÷ 4 = 194,363,156.75
If the quotient is a whole number, then 4 and 194,363,156.75 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 | 777,452,627 | |
| -1 | 777,452,627 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 71 | 217 | 497 | 2,201 | 15,407 | 50,461 | 353,227 | 1,564,291 | 3,582,731 | 10,950,037 | 25,079,117 | 111,064,661 | 777,452,627 |
| -1 | -7 | -31 | -71 | -217 | -497 | -2,201 | -15,407 | -50,461 | -353,227 | -1,564,291 | -3,582,731 | -10,950,037 | -25,079,117 | -111,064,661 | -777,452,627 |
