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 67,027,549, 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 | 67,027,549 | |
| -1 | -67,027,549 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,027,549.
Example:
1 x 67,027,549 = 67,027,549
and
-1 x -67,027,549 = 67,027,549
Notice both answers equal 67,027,549
With that explanation out of the way, let's continue. Next, we take the number 67,027,549 and divide it by 2:
67,027,549 ÷ 2 = 33,513,774.5
If the quotient is a whole number, then 2 and 33,513,774.5 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 | 67,027,549 | |
| -1 | -67,027,549 |
Now, we try dividing 67,027,549 by 3:
67,027,549 ÷ 3 = 22,342,516.3333
If the quotient is a whole number, then 3 and 22,342,516.3333 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 | 67,027,549 | |
| -1 | -67,027,549 |
Let's try dividing by 4:
67,027,549 ÷ 4 = 16,756,887.25
If the quotient is a whole number, then 4 and 16,756,887.25 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 | 67,027,549 | |
| -1 | 67,027,549 |
If you did it right, you will end up with this table:
| 1 | 17 | 31 | 193 | 527 | 659 | 3,281 | 5,983 | 11,203 | 20,429 | 101,711 | 127,187 | 347,293 | 2,162,179 | 3,942,797 | 67,027,549 |
| -1 | -17 | -31 | -193 | -527 | -659 | -3,281 | -5,983 | -11,203 | -20,429 | -101,711 | -127,187 | -347,293 | -2,162,179 | -3,942,797 | -67,027,549 |
