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 103,343,863, 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 | 103,343,863 | |
| -1 | -103,343,863 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,343,863.
Example:
1 x 103,343,863 = 103,343,863
and
-1 x -103,343,863 = 103,343,863
Notice both answers equal 103,343,863
With that explanation out of the way, let's continue. Next, we take the number 103,343,863 and divide it by 2:
103,343,863 ÷ 2 = 51,671,931.5
If the quotient is a whole number, then 2 and 51,671,931.5 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 | 103,343,863 | |
| -1 | -103,343,863 |
Now, we try dividing 103,343,863 by 3:
103,343,863 ÷ 3 = 34,447,954.3333
If the quotient is a whole number, then 3 and 34,447,954.3333 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 | 103,343,863 | |
| -1 | -103,343,863 |
Let's try dividing by 4:
103,343,863 ÷ 4 = 25,835,965.75
If the quotient is a whole number, then 4 and 25,835,965.75 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 | 103,343,863 | |
| -1 | 103,343,863 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 89 | 217 | 623 | 2,759 | 5,351 | 19,313 | 37,457 | 165,881 | 476,239 | 1,161,167 | 3,333,673 | 14,763,409 | 103,343,863 |
| -1 | -7 | -31 | -89 | -217 | -623 | -2,759 | -5,351 | -19,313 | -37,457 | -165,881 | -476,239 | -1,161,167 | -3,333,673 | -14,763,409 | -103,343,863 |
