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 60,541,505, 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 | 60,541,505 | |
| -1 | -60,541,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,541,505.
Example:
1 x 60,541,505 = 60,541,505
and
-1 x -60,541,505 = 60,541,505
Notice both answers equal 60,541,505
With that explanation out of the way, let's continue. Next, we take the number 60,541,505 and divide it by 2:
60,541,505 ÷ 2 = 30,270,752.5
If the quotient is a whole number, then 2 and 30,270,752.5 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 | 60,541,505 | |
| -1 | -60,541,505 |
Now, we try dividing 60,541,505 by 3:
60,541,505 ÷ 3 = 20,180,501.6667
If the quotient is a whole number, then 3 and 20,180,501.6667 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 | 60,541,505 | |
| -1 | -60,541,505 |
Let's try dividing by 4:
60,541,505 ÷ 4 = 15,135,376.25
If the quotient is a whole number, then 4 and 15,135,376.25 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 | 60,541,505 | |
| -1 | 60,541,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 19 | 85 | 95 | 323 | 361 | 1,615 | 1,805 | 1,973 | 6,137 | 9,865 | 30,685 | 33,541 | 37,487 | 167,705 | 187,435 | 637,279 | 712,253 | 3,186,395 | 3,561,265 | 12,108,301 | 60,541,505 |
| -1 | -5 | -17 | -19 | -85 | -95 | -323 | -361 | -1,615 | -1,805 | -1,973 | -6,137 | -9,865 | -30,685 | -33,541 | -37,487 | -167,705 | -187,435 | -637,279 | -712,253 | -3,186,395 | -3,561,265 | -12,108,301 | -60,541,505 |
