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 7,766,671, 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 | 7,766,671 | |
| -1 | -7,766,671 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,766,671.
Example:
1 x 7,766,671 = 7,766,671
and
-1 x -7,766,671 = 7,766,671
Notice both answers equal 7,766,671
With that explanation out of the way, let's continue. Next, we take the number 7,766,671 and divide it by 2:
7,766,671 ÷ 2 = 3,883,335.5
If the quotient is a whole number, then 2 and 3,883,335.5 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 | 7,766,671 | |
| -1 | -7,766,671 |
Now, we try dividing 7,766,671 by 3:
7,766,671 ÷ 3 = 2,588,890.3333
If the quotient is a whole number, then 3 and 2,588,890.3333 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 | 7,766,671 | |
| -1 | -7,766,671 |
Let's try dividing by 4:
7,766,671 ÷ 4 = 1,941,667.75
If the quotient is a whole number, then 4 and 1,941,667.75 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 | 7,766,671 | |
| -1 | 7,766,671 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 41 | 187 | 451 | 697 | 1,013 | 7,667 | 11,143 | 17,221 | 41,533 | 189,431 | 456,863 | 706,061 | 7,766,671 |
| -1 | -11 | -17 | -41 | -187 | -451 | -697 | -1,013 | -7,667 | -11,143 | -17,221 | -41,533 | -189,431 | -456,863 | -706,061 | -7,766,671 |
