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 67,898,495, 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 | 67,898,495 | |
| -1 | -67,898,495 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,898,495.
Example:
1 x 67,898,495 = 67,898,495
and
-1 x -67,898,495 = 67,898,495
Notice both answers equal 67,898,495
With that explanation out of the way, let's continue. Next, we take the number 67,898,495 and divide it by 2:
67,898,495 ÷ 2 = 33,949,247.5
If the quotient is a whole number, then 2 and 33,949,247.5 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 | 67,898,495 | |
| -1 | -67,898,495 |
Now, we try dividing 67,898,495 by 3:
67,898,495 ÷ 3 = 22,632,831.6667
If the quotient is a whole number, then 3 and 22,632,831.6667 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 | 67,898,495 | |
| -1 | -67,898,495 |
Let's try dividing by 4:
67,898,495 ÷ 4 = 16,974,623.75
If the quotient is a whole number, then 4 and 16,974,623.75 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 | 67,898,495 | |
| -1 | 67,898,495 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 102,103 | 510,515 | 714,721 | 1,939,957 | 3,573,605 | 9,699,785 | 13,579,699 | 67,898,495 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -102,103 | -510,515 | -714,721 | -1,939,957 | -3,573,605 | -9,699,785 | -13,579,699 | -67,898,495 |
