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 103,292,845, 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 | 103,292,845 | |
| -1 | -103,292,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,292,845.
Example:
1 x 103,292,845 = 103,292,845
and
-1 x -103,292,845 = 103,292,845
Notice both answers equal 103,292,845
With that explanation out of the way, let's continue. Next, we take the number 103,292,845 and divide it by 2:
103,292,845 ÷ 2 = 51,646,422.5
If the quotient is a whole number, then 2 and 51,646,422.5 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 | 103,292,845 | |
| -1 | -103,292,845 |
Now, we try dividing 103,292,845 by 3:
103,292,845 ÷ 3 = 34,430,948.3333
If the quotient is a whole number, then 3 and 34,430,948.3333 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 | 103,292,845 | |
| -1 | -103,292,845 |
Let's try dividing by 4:
103,292,845 ÷ 4 = 25,823,211.25
If the quotient is a whole number, then 4 and 25,823,211.25 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 | 103,292,845 | |
| -1 | 103,292,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 131 | 179 | 655 | 881 | 895 | 4,405 | 23,449 | 115,411 | 117,245 | 157,699 | 577,055 | 788,495 | 20,658,569 | 103,292,845 |
| -1 | -5 | -131 | -179 | -655 | -881 | -895 | -4,405 | -23,449 | -115,411 | -117,245 | -157,699 | -577,055 | -788,495 | -20,658,569 | -103,292,845 |
