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 67,017,115, 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 | 67,017,115 | |
| -1 | -67,017,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,017,115.
Example:
1 x 67,017,115 = 67,017,115
and
-1 x -67,017,115 = 67,017,115
Notice both answers equal 67,017,115
With that explanation out of the way, let's continue. Next, we take the number 67,017,115 and divide it by 2:
67,017,115 ÷ 2 = 33,508,557.5
If the quotient is a whole number, then 2 and 33,508,557.5 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 | 67,017,115 | |
| -1 | -67,017,115 |
Now, we try dividing 67,017,115 by 3:
67,017,115 ÷ 3 = 22,339,038.3333
If the quotient is a whole number, then 3 and 22,339,038.3333 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 | 67,017,115 | |
| -1 | -67,017,115 |
Let's try dividing by 4:
67,017,115 ÷ 4 = 16,754,278.75
If the quotient is a whole number, then 4 and 16,754,278.75 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 | 67,017,115 | |
| -1 | 67,017,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 42,017 | 210,085 | 462,187 | 1,218,493 | 2,310,935 | 6,092,465 | 13,403,423 | 67,017,115 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -42,017 | -210,085 | -462,187 | -1,218,493 | -2,310,935 | -6,092,465 | -13,403,423 | -67,017,115 |
