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 103,141,465, 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 | 103,141,465 | |
| -1 | -103,141,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,141,465.
Example:
1 x 103,141,465 = 103,141,465
and
-1 x -103,141,465 = 103,141,465
Notice both answers equal 103,141,465
With that explanation out of the way, let's continue. Next, we take the number 103,141,465 and divide it by 2:
103,141,465 ÷ 2 = 51,570,732.5
If the quotient is a whole number, then 2 and 51,570,732.5 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 | 103,141,465 | |
| -1 | -103,141,465 |
Now, we try dividing 103,141,465 by 3:
103,141,465 ÷ 3 = 34,380,488.3333
If the quotient is a whole number, then 3 and 34,380,488.3333 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 | 103,141,465 | |
| -1 | -103,141,465 |
Let's try dividing by 4:
103,141,465 ÷ 4 = 25,785,366.25
If the quotient is a whole number, then 4 and 25,785,366.25 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 | 103,141,465 | |
| -1 | 103,141,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 173,347 | 866,735 | 1,213,429 | 2,946,899 | 6,067,145 | 14,734,495 | 20,628,293 | 103,141,465 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -173,347 | -866,735 | -1,213,429 | -2,946,899 | -6,067,145 | -14,734,495 | -20,628,293 | -103,141,465 |
