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 67,000,703, 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 | 67,000,703 | |
| -1 | -67,000,703 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,000,703.
Example:
1 x 67,000,703 = 67,000,703
and
-1 x -67,000,703 = 67,000,703
Notice both answers equal 67,000,703
With that explanation out of the way, let's continue. Next, we take the number 67,000,703 and divide it by 2:
67,000,703 ÷ 2 = 33,500,351.5
If the quotient is a whole number, then 2 and 33,500,351.5 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 | 67,000,703 | |
| -1 | -67,000,703 |
Now, we try dividing 67,000,703 by 3:
67,000,703 ÷ 3 = 22,333,567.6667
If the quotient is a whole number, then 3 and 22,333,567.6667 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 | 67,000,703 | |
| -1 | -67,000,703 |
Let's try dividing by 4:
67,000,703 ÷ 4 = 16,750,175.75
If the quotient is a whole number, then 4 and 16,750,175.75 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 | 67,000,703 | |
| -1 | 67,000,703 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 77 | 217 | 341 | 2,387 | 28,069 | 196,483 | 308,759 | 870,139 | 2,161,313 | 6,090,973 | 9,571,529 | 67,000,703 |
| -1 | -7 | -11 | -31 | -77 | -217 | -341 | -2,387 | -28,069 | -196,483 | -308,759 | -870,139 | -2,161,313 | -6,090,973 | -9,571,529 | -67,000,703 |
