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 67,222,265, 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 | 67,222,265 | |
| -1 | -67,222,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,222,265.
Example:
1 x 67,222,265 = 67,222,265
and
-1 x -67,222,265 = 67,222,265
Notice both answers equal 67,222,265
With that explanation out of the way, let's continue. Next, we take the number 67,222,265 and divide it by 2:
67,222,265 ÷ 2 = 33,611,132.5
If the quotient is a whole number, then 2 and 33,611,132.5 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 | 67,222,265 | |
| -1 | -67,222,265 |
Now, we try dividing 67,222,265 by 3:
67,222,265 ÷ 3 = 22,407,421.6667
If the quotient is a whole number, then 3 and 22,407,421.6667 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 | 67,222,265 | |
| -1 | -67,222,265 |
Let's try dividing by 4:
67,222,265 ÷ 4 = 16,805,566.25
If the quotient is a whole number, then 4 and 16,805,566.25 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 | 67,222,265 | |
| -1 | 67,222,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 419 | 2,095 | 2,917 | 4,609 | 14,585 | 23,045 | 32,087 | 160,435 | 1,222,223 | 6,111,115 | 13,444,453 | 67,222,265 |
| -1 | -5 | -11 | -55 | -419 | -2,095 | -2,917 | -4,609 | -14,585 | -23,045 | -32,087 | -160,435 | -1,222,223 | -6,111,115 | -13,444,453 | -67,222,265 |
