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 67,045,205, 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 | 67,045,205 | |
| -1 | -67,045,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,045,205.
Example:
1 x 67,045,205 = 67,045,205
and
-1 x -67,045,205 = 67,045,205
Notice both answers equal 67,045,205
With that explanation out of the way, let's continue. Next, we take the number 67,045,205 and divide it by 2:
67,045,205 ÷ 2 = 33,522,602.5
If the quotient is a whole number, then 2 and 33,522,602.5 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 | 67,045,205 | |
| -1 | -67,045,205 |
Now, we try dividing 67,045,205 by 3:
67,045,205 ÷ 3 = 22,348,401.6667
If the quotient is a whole number, then 3 and 22,348,401.6667 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 | 67,045,205 | |
| -1 | -67,045,205 |
Let's try dividing by 4:
67,045,205 ÷ 4 = 16,761,301.25
If the quotient is a whole number, then 4 and 16,761,301.25 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 | 67,045,205 | |
| -1 | 67,045,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 127 | 635 | 2,413 | 5,557 | 12,065 | 27,785 | 105,583 | 527,915 | 705,739 | 3,528,695 | 13,409,041 | 67,045,205 |
| -1 | -5 | -19 | -95 | -127 | -635 | -2,413 | -5,557 | -12,065 | -27,785 | -105,583 | -527,915 | -705,739 | -3,528,695 | -13,409,041 | -67,045,205 |
