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 67,697,645, 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 | 67,697,645 | |
| -1 | -67,697,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,697,645.
Example:
1 x 67,697,645 = 67,697,645
and
-1 x -67,697,645 = 67,697,645
Notice both answers equal 67,697,645
With that explanation out of the way, let's continue. Next, we take the number 67,697,645 and divide it by 2:
67,697,645 ÷ 2 = 33,848,822.5
If the quotient is a whole number, then 2 and 33,848,822.5 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 | 67,697,645 | |
| -1 | -67,697,645 |
Now, we try dividing 67,697,645 by 3:
67,697,645 ÷ 3 = 22,565,881.6667
If the quotient is a whole number, then 3 and 22,565,881.6667 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 | 67,697,645 | |
| -1 | -67,697,645 |
Let's try dividing by 4:
67,697,645 ÷ 4 = 16,924,411.25
If the quotient is a whole number, then 4 and 16,924,411.25 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 | 67,697,645 | |
| -1 | 67,697,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 73 | 155 | 193 | 365 | 961 | 965 | 2,263 | 4,805 | 5,983 | 11,315 | 14,089 | 29,915 | 70,153 | 70,445 | 185,473 | 350,765 | 436,759 | 927,365 | 2,183,795 | 13,539,529 | 67,697,645 |
| -1 | -5 | -31 | -73 | -155 | -193 | -365 | -961 | -965 | -2,263 | -4,805 | -5,983 | -11,315 | -14,089 | -29,915 | -70,153 | -70,445 | -185,473 | -350,765 | -436,759 | -927,365 | -2,183,795 | -13,539,529 | -67,697,645 |
