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 103,263,577, 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 | 103,263,577 | |
| -1 | -103,263,577 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,263,577.
Example:
1 x 103,263,577 = 103,263,577
and
-1 x -103,263,577 = 103,263,577
Notice both answers equal 103,263,577
With that explanation out of the way, let's continue. Next, we take the number 103,263,577 and divide it by 2:
103,263,577 ÷ 2 = 51,631,788.5
If the quotient is a whole number, then 2 and 51,631,788.5 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 | 103,263,577 | |
| -1 | -103,263,577 |
Now, we try dividing 103,263,577 by 3:
103,263,577 ÷ 3 = 34,421,192.3333
If the quotient is a whole number, then 3 and 34,421,192.3333 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 | 103,263,577 | |
| -1 | -103,263,577 |
Let's try dividing by 4:
103,263,577 ÷ 4 = 25,815,894.25
If the quotient is a whole number, then 4 and 25,815,894.25 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 | 103,263,577 | |
| -1 | 103,263,577 |
If you did it right, you will end up with this table:
| 1 | 29 | 103 | 181 | 191 | 2,987 | 5,249 | 5,539 | 18,643 | 19,673 | 34,571 | 540,647 | 570,517 | 1,002,559 | 3,560,813 | 103,263,577 |
| -1 | -29 | -103 | -181 | -191 | -2,987 | -5,249 | -5,539 | -18,643 | -19,673 | -34,571 | -540,647 | -570,517 | -1,002,559 | -3,560,813 | -103,263,577 |
