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 103,643,195, 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 | 103,643,195 | |
| -1 | -103,643,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,643,195.
Example:
1 x 103,643,195 = 103,643,195
and
-1 x -103,643,195 = 103,643,195
Notice both answers equal 103,643,195
With that explanation out of the way, let's continue. Next, we take the number 103,643,195 and divide it by 2:
103,643,195 ÷ 2 = 51,821,597.5
If the quotient is a whole number, then 2 and 51,821,597.5 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 | 103,643,195 | |
| -1 | -103,643,195 |
Now, we try dividing 103,643,195 by 3:
103,643,195 ÷ 3 = 34,547,731.6667
If the quotient is a whole number, then 3 and 34,547,731.6667 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 | 103,643,195 | |
| -1 | -103,643,195 |
Let's try dividing by 4:
103,643,195 ÷ 4 = 25,910,798.75
If the quotient is a whole number, then 4 and 25,910,798.75 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 | 103,643,195 | |
| -1 | 103,643,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 109 | 545 | 2,071 | 10,009 | 10,355 | 50,045 | 190,171 | 950,855 | 1,090,981 | 5,454,905 | 20,728,639 | 103,643,195 |
| -1 | -5 | -19 | -95 | -109 | -545 | -2,071 | -10,009 | -10,355 | -50,045 | -190,171 | -950,855 | -1,090,981 | -5,454,905 | -20,728,639 | -103,643,195 |
