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 7,662,643, 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 | 7,662,643 | |
| -1 | -7,662,643 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,662,643.
Example:
1 x 7,662,643 = 7,662,643
and
-1 x -7,662,643 = 7,662,643
Notice both answers equal 7,662,643
With that explanation out of the way, let's continue. Next, we take the number 7,662,643 and divide it by 2:
7,662,643 ÷ 2 = 3,831,321.5
If the quotient is a whole number, then 2 and 3,831,321.5 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 | 7,662,643 | |
| -1 | -7,662,643 |
Now, we try dividing 7,662,643 by 3:
7,662,643 ÷ 3 = 2,554,214.3333
If the quotient is a whole number, then 3 and 2,554,214.3333 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 | 7,662,643 | |
| -1 | -7,662,643 |
Let's try dividing by 4:
7,662,643 ÷ 4 = 1,915,660.75
If the quotient is a whole number, then 4 and 1,915,660.75 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 | 7,662,643 | |
| -1 | 7,662,643 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 83 | 113 | 817 | 1,577 | 2,147 | 3,569 | 4,859 | 9,379 | 67,811 | 92,321 | 178,201 | 403,297 | 7,662,643 |
| -1 | -19 | -43 | -83 | -113 | -817 | -1,577 | -2,147 | -3,569 | -4,859 | -9,379 | -67,811 | -92,321 | -178,201 | -403,297 | -7,662,643 |
