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 103,654,405, 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 | 103,654,405 | |
| -1 | -103,654,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,654,405.
Example:
1 x 103,654,405 = 103,654,405
and
-1 x -103,654,405 = 103,654,405
Notice both answers equal 103,654,405
With that explanation out of the way, let's continue. Next, we take the number 103,654,405 and divide it by 2:
103,654,405 ÷ 2 = 51,827,202.5
If the quotient is a whole number, then 2 and 51,827,202.5 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 | 103,654,405 | |
| -1 | -103,654,405 |
Now, we try dividing 103,654,405 by 3:
103,654,405 ÷ 3 = 34,551,468.3333
If the quotient is a whole number, then 3 and 34,551,468.3333 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 | 103,654,405 | |
| -1 | -103,654,405 |
Let's try dividing by 4:
103,654,405 ÷ 4 = 25,913,601.25
If the quotient is a whole number, then 4 and 25,913,601.25 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 | 103,654,405 | |
| -1 | 103,654,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 131 | 655 | 2,489 | 8,329 | 12,445 | 41,645 | 158,251 | 791,255 | 1,091,099 | 5,455,495 | 20,730,881 | 103,654,405 |
| -1 | -5 | -19 | -95 | -131 | -655 | -2,489 | -8,329 | -12,445 | -41,645 | -158,251 | -791,255 | -1,091,099 | -5,455,495 | -20,730,881 | -103,654,405 |
