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 67,796,663, 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 | 67,796,663 | |
| -1 | -67,796,663 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,796,663.
Example:
1 x 67,796,663 = 67,796,663
and
-1 x -67,796,663 = 67,796,663
Notice both answers equal 67,796,663
With that explanation out of the way, let's continue. Next, we take the number 67,796,663 and divide it by 2:
67,796,663 ÷ 2 = 33,898,331.5
If the quotient is a whole number, then 2 and 33,898,331.5 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 | 67,796,663 | |
| -1 | -67,796,663 |
Now, we try dividing 67,796,663 by 3:
67,796,663 ÷ 3 = 22,598,887.6667
If the quotient is a whole number, then 3 and 22,598,887.6667 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 | 67,796,663 | |
| -1 | -67,796,663 |
Let's try dividing by 4:
67,796,663 ÷ 4 = 16,949,165.75
If the quotient is a whole number, then 4 and 16,949,165.75 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 | 67,796,663 | |
| -1 | 67,796,663 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 23 | 121 | 187 | 253 | 391 | 1,433 | 2,057 | 2,783 | 4,301 | 15,763 | 24,361 | 32,959 | 47,311 | 173,393 | 267,971 | 362,549 | 560,303 | 2,947,681 | 3,988,039 | 6,163,333 | 67,796,663 |
| -1 | -11 | -17 | -23 | -121 | -187 | -253 | -391 | -1,433 | -2,057 | -2,783 | -4,301 | -15,763 | -24,361 | -32,959 | -47,311 | -173,393 | -267,971 | -362,549 | -560,303 | -2,947,681 | -3,988,039 | -6,163,333 | -67,796,663 |
