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 67,025,365, 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 | 67,025,365 | |
| -1 | -67,025,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,025,365.
Example:
1 x 67,025,365 = 67,025,365
and
-1 x -67,025,365 = 67,025,365
Notice both answers equal 67,025,365
With that explanation out of the way, let's continue. Next, we take the number 67,025,365 and divide it by 2:
67,025,365 ÷ 2 = 33,512,682.5
If the quotient is a whole number, then 2 and 33,512,682.5 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 | 67,025,365 | |
| -1 | -67,025,365 |
Now, we try dividing 67,025,365 by 3:
67,025,365 ÷ 3 = 22,341,788.3333
If the quotient is a whole number, then 3 and 22,341,788.3333 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 | 67,025,365 | |
| -1 | -67,025,365 |
Let's try dividing by 4:
67,025,365 ÷ 4 = 16,756,341.25
If the quotient is a whole number, then 4 and 16,756,341.25 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 | 67,025,365 | |
| -1 | 67,025,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 41 | 55 | 205 | 451 | 2,255 | 29,723 | 148,615 | 326,953 | 1,218,643 | 1,634,765 | 6,093,215 | 13,405,073 | 67,025,365 |
| -1 | -5 | -11 | -41 | -55 | -205 | -451 | -2,255 | -29,723 | -148,615 | -326,953 | -1,218,643 | -1,634,765 | -6,093,215 | -13,405,073 | -67,025,365 |
