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 102,413,051, 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 | 102,413,051 | |
| -1 | -102,413,051 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,413,051.
Example:
1 x 102,413,051 = 102,413,051
and
-1 x -102,413,051 = 102,413,051
Notice both answers equal 102,413,051
With that explanation out of the way, let's continue. Next, we take the number 102,413,051 and divide it by 2:
102,413,051 ÷ 2 = 51,206,525.5
If the quotient is a whole number, then 2 and 51,206,525.5 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 | 102,413,051 | |
| -1 | -102,413,051 |
Now, we try dividing 102,413,051 by 3:
102,413,051 ÷ 3 = 34,137,683.6667
If the quotient is a whole number, then 3 and 34,137,683.6667 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 | 102,413,051 | |
| -1 | -102,413,051 |
Let's try dividing by 4:
102,413,051 ÷ 4 = 25,603,262.75
If the quotient is a whole number, then 4 and 25,603,262.75 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 | 102,413,051 | |
| -1 | 102,413,051 |
If you did it right, you will end up with this table:
| 1 | 13 | 67 | 307 | 383 | 871 | 3,991 | 4,979 | 20,569 | 25,661 | 117,581 | 267,397 | 333,593 | 1,528,553 | 7,877,927 | 102,413,051 |
| -1 | -13 | -67 | -307 | -383 | -871 | -3,991 | -4,979 | -20,569 | -25,661 | -117,581 | -267,397 | -333,593 | -1,528,553 | -7,877,927 | -102,413,051 |
