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 67,476,685, 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 | 67,476,685 | |
| -1 | -67,476,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,476,685.
Example:
1 x 67,476,685 = 67,476,685
and
-1 x -67,476,685 = 67,476,685
Notice both answers equal 67,476,685
With that explanation out of the way, let's continue. Next, we take the number 67,476,685 and divide it by 2:
67,476,685 ÷ 2 = 33,738,342.5
If the quotient is a whole number, then 2 and 33,738,342.5 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 | 67,476,685 | |
| -1 | -67,476,685 |
Now, we try dividing 67,476,685 by 3:
67,476,685 ÷ 3 = 22,492,228.3333
If the quotient is a whole number, then 3 and 22,492,228.3333 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 | 67,476,685 | |
| -1 | -67,476,685 |
Let's try dividing by 4:
67,476,685 ÷ 4 = 16,869,171.25
If the quotient is a whole number, then 4 and 16,869,171.25 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 | 67,476,685 | |
| -1 | 67,476,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 89 | 265 | 445 | 2,861 | 4,717 | 14,305 | 23,585 | 151,633 | 254,629 | 758,165 | 1,273,145 | 13,495,337 | 67,476,685 |
| -1 | -5 | -53 | -89 | -265 | -445 | -2,861 | -4,717 | -14,305 | -23,585 | -151,633 | -254,629 | -758,165 | -1,273,145 | -13,495,337 | -67,476,685 |
