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 67,402,775, 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 | 67,402,775 | |
| -1 | -67,402,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,402,775.
Example:
1 x 67,402,775 = 67,402,775
and
-1 x -67,402,775 = 67,402,775
Notice both answers equal 67,402,775
With that explanation out of the way, let's continue. Next, we take the number 67,402,775 and divide it by 2:
67,402,775 ÷ 2 = 33,701,387.5
If the quotient is a whole number, then 2 and 33,701,387.5 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 | 67,402,775 | |
| -1 | -67,402,775 |
Now, we try dividing 67,402,775 by 3:
67,402,775 ÷ 3 = 22,467,591.6667
If the quotient is a whole number, then 3 and 22,467,591.6667 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 | 67,402,775 | |
| -1 | -67,402,775 |
Let's try dividing by 4:
67,402,775 ÷ 4 = 16,850,693.75
If the quotient is a whole number, then 4 and 16,850,693.75 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 | 67,402,775 | |
| -1 | 67,402,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 131 | 275 | 655 | 1,441 | 1,871 | 3,275 | 7,205 | 9,355 | 20,581 | 36,025 | 46,775 | 102,905 | 245,101 | 514,525 | 1,225,505 | 2,696,111 | 6,127,525 | 13,480,555 | 67,402,775 |
| -1 | -5 | -11 | -25 | -55 | -131 | -275 | -655 | -1,441 | -1,871 | -3,275 | -7,205 | -9,355 | -20,581 | -36,025 | -46,775 | -102,905 | -245,101 | -514,525 | -1,225,505 | -2,696,111 | -6,127,525 | -13,480,555 | -67,402,775 |
