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 60,417,245, 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 | 60,417,245 | |
| -1 | -60,417,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,417,245.
Example:
1 x 60,417,245 = 60,417,245
and
-1 x -60,417,245 = 60,417,245
Notice both answers equal 60,417,245
With that explanation out of the way, let's continue. Next, we take the number 60,417,245 and divide it by 2:
60,417,245 ÷ 2 = 30,208,622.5
If the quotient is a whole number, then 2 and 30,208,622.5 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 | 60,417,245 | |
| -1 | -60,417,245 |
Now, we try dividing 60,417,245 by 3:
60,417,245 ÷ 3 = 20,139,081.6667
If the quotient is a whole number, then 3 and 20,139,081.6667 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 | 60,417,245 | |
| -1 | -60,417,245 |
Let's try dividing by 4:
60,417,245 ÷ 4 = 15,104,311.25
If the quotient is a whole number, then 4 and 15,104,311.25 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 | 60,417,245 | |
| -1 | 60,417,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 49 | 95 | 133 | 245 | 665 | 931 | 4,655 | 12,979 | 64,895 | 90,853 | 246,601 | 454,265 | 635,971 | 1,233,005 | 1,726,207 | 3,179,855 | 8,631,035 | 12,083,449 | 60,417,245 |
| -1 | -5 | -7 | -19 | -35 | -49 | -95 | -133 | -245 | -665 | -931 | -4,655 | -12,979 | -64,895 | -90,853 | -246,601 | -454,265 | -635,971 | -1,233,005 | -1,726,207 | -3,179,855 | -8,631,035 | -12,083,449 | -60,417,245 |
