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 60,540,781, 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 | 60,540,781 | |
| -1 | -60,540,781 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,540,781.
Example:
1 x 60,540,781 = 60,540,781
and
-1 x -60,540,781 = 60,540,781
Notice both answers equal 60,540,781
With that explanation out of the way, let's continue. Next, we take the number 60,540,781 and divide it by 2:
60,540,781 ÷ 2 = 30,270,390.5
If the quotient is a whole number, then 2 and 30,270,390.5 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 | 60,540,781 | |
| -1 | -60,540,781 |
Now, we try dividing 60,540,781 by 3:
60,540,781 ÷ 3 = 20,180,260.3333
If the quotient is a whole number, then 3 and 20,180,260.3333 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 | 60,540,781 | |
| -1 | -60,540,781 |
Let's try dividing by 4:
60,540,781 ÷ 4 = 15,135,195.25
If the quotient is a whole number, then 4 and 15,135,195.25 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 | 60,540,781 | |
| -1 | 60,540,781 |
If you did it right, you will end up with this table:
| 1 | 7 | 79 | 83 | 553 | 581 | 1,319 | 6,557 | 9,233 | 45,899 | 104,201 | 109,477 | 729,407 | 766,339 | 8,648,683 | 60,540,781 |
| -1 | -7 | -79 | -83 | -553 | -581 | -1,319 | -6,557 | -9,233 | -45,899 | -104,201 | -109,477 | -729,407 | -766,339 | -8,648,683 | -60,540,781 |
