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 103,868,521, 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 | 103,868,521 | |
| -1 | -103,868,521 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,868,521.
Example:
1 x 103,868,521 = 103,868,521
and
-1 x -103,868,521 = 103,868,521
Notice both answers equal 103,868,521
With that explanation out of the way, let's continue. Next, we take the number 103,868,521 and divide it by 2:
103,868,521 ÷ 2 = 51,934,260.5
If the quotient is a whole number, then 2 and 51,934,260.5 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 | 103,868,521 | |
| -1 | -103,868,521 |
Now, we try dividing 103,868,521 by 3:
103,868,521 ÷ 3 = 34,622,840.3333
If the quotient is a whole number, then 3 and 34,622,840.3333 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 | 103,868,521 | |
| -1 | -103,868,521 |
Let's try dividing by 4:
103,868,521 ÷ 4 = 25,967,130.25
If the quotient is a whole number, then 4 and 25,967,130.25 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 | 103,868,521 | |
| -1 | 103,868,521 |
If you did it right, you will end up with this table:
| 1 | 17 | 43 | 151 | 731 | 941 | 2,567 | 6,493 | 15,997 | 40,463 | 110,381 | 142,091 | 687,871 | 2,415,547 | 6,109,913 | 103,868,521 |
| -1 | -17 | -43 | -151 | -731 | -941 | -2,567 | -6,493 | -15,997 | -40,463 | -110,381 | -142,091 | -687,871 | -2,415,547 | -6,109,913 | -103,868,521 |
