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 67,624,625, 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 | 67,624,625 | |
| -1 | -67,624,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,624,625.
Example:
1 x 67,624,625 = 67,624,625
and
-1 x -67,624,625 = 67,624,625
Notice both answers equal 67,624,625
With that explanation out of the way, let's continue. Next, we take the number 67,624,625 and divide it by 2:
67,624,625 ÷ 2 = 33,812,312.5
If the quotient is a whole number, then 2 and 33,812,312.5 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 | 67,624,625 | |
| -1 | -67,624,625 |
Now, we try dividing 67,624,625 by 3:
67,624,625 ÷ 3 = 22,541,541.6667
If the quotient is a whole number, then 3 and 22,541,541.6667 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 | 67,624,625 | |
| -1 | -67,624,625 |
Let's try dividing by 4:
67,624,625 ÷ 4 = 16,906,156.25
If the quotient is a whole number, then 4 and 16,906,156.25 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 | 67,624,625 | |
| -1 | 67,624,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 163 | 815 | 3,319 | 4,075 | 16,595 | 20,375 | 82,975 | 414,875 | 540,997 | 2,704,985 | 13,524,925 | 67,624,625 |
| -1 | -5 | -25 | -125 | -163 | -815 | -3,319 | -4,075 | -16,595 | -20,375 | -82,975 | -414,875 | -540,997 | -2,704,985 | -13,524,925 | -67,624,625 |
