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 73,753,871, 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 | 73,753,871 | |
| -1 | -73,753,871 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 73,753,871.
Example:
1 x 73,753,871 = 73,753,871
and
-1 x -73,753,871 = 73,753,871
Notice both answers equal 73,753,871
With that explanation out of the way, let's continue. Next, we take the number 73,753,871 and divide it by 2:
73,753,871 ÷ 2 = 36,876,935.5
If the quotient is a whole number, then 2 and 36,876,935.5 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 | 73,753,871 | |
| -1 | -73,753,871 |
Now, we try dividing 73,753,871 by 3:
73,753,871 ÷ 3 = 24,584,623.6667
If the quotient is a whole number, then 3 and 24,584,623.6667 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 | 73,753,871 | |
| -1 | -73,753,871 |
Let's try dividing by 4:
73,753,871 ÷ 4 = 18,438,467.75
If the quotient is a whole number, then 4 and 18,438,467.75 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 | 73,753,871 | |
| -1 | 73,753,871 |
If you did it right, you will end up with this table:
| 1 | 17 | 73 | 103 | 577 | 1,241 | 1,751 | 7,519 | 9,809 | 42,121 | 59,431 | 127,823 | 716,057 | 1,010,327 | 4,338,463 | 73,753,871 |
| -1 | -17 | -73 | -103 | -577 | -1,241 | -1,751 | -7,519 | -9,809 | -42,121 | -59,431 | -127,823 | -716,057 | -1,010,327 | -4,338,463 | -73,753,871 |
