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 67,493,339, 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 | 67,493,339 | |
| -1 | -67,493,339 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,493,339.
Example:
1 x 67,493,339 = 67,493,339
and
-1 x -67,493,339 = 67,493,339
Notice both answers equal 67,493,339
With that explanation out of the way, let's continue. Next, we take the number 67,493,339 and divide it by 2:
67,493,339 ÷ 2 = 33,746,669.5
If the quotient is a whole number, then 2 and 33,746,669.5 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 | 67,493,339 | |
| -1 | -67,493,339 |
Now, we try dividing 67,493,339 by 3:
67,493,339 ÷ 3 = 22,497,779.6667
If the quotient is a whole number, then 3 and 22,497,779.6667 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 | 67,493,339 | |
| -1 | -67,493,339 |
Let's try dividing by 4:
67,493,339 ÷ 4 = 16,873,334.75
If the quotient is a whole number, then 4 and 16,873,334.75 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 | 67,493,339 | |
| -1 | 67,493,339 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 41 | 437 | 779 | 943 | 3,767 | 17,917 | 71,573 | 86,641 | 154,447 | 1,646,179 | 2,934,493 | 3,552,281 | 67,493,339 |
| -1 | -19 | -23 | -41 | -437 | -779 | -943 | -3,767 | -17,917 | -71,573 | -86,641 | -154,447 | -1,646,179 | -2,934,493 | -3,552,281 | -67,493,339 |
