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 60,034,247, 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 | 60,034,247 | |
| -1 | -60,034,247 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,034,247.
Example:
1 x 60,034,247 = 60,034,247
and
-1 x -60,034,247 = 60,034,247
Notice both answers equal 60,034,247
With that explanation out of the way, let's continue. Next, we take the number 60,034,247 and divide it by 2:
60,034,247 ÷ 2 = 30,017,123.5
If the quotient is a whole number, then 2 and 30,017,123.5 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 | 60,034,247 | |
| -1 | -60,034,247 |
Now, we try dividing 60,034,247 by 3:
60,034,247 ÷ 3 = 20,011,415.6667
If the quotient is a whole number, then 3 and 20,011,415.6667 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 | 60,034,247 | |
| -1 | -60,034,247 |
Let's try dividing by 4:
60,034,247 ÷ 4 = 15,008,561.75
If the quotient is a whole number, then 4 and 15,008,561.75 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 | 60,034,247 | |
| -1 | 60,034,247 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 409 | 1,613 | 2,863 | 5,317 | 11,291 | 20,969 | 37,219 | 146,783 | 659,717 | 4,618,019 | 8,576,321 | 60,034,247 |
| -1 | -7 | -13 | -91 | -409 | -1,613 | -2,863 | -5,317 | -11,291 | -20,969 | -37,219 | -146,783 | -659,717 | -4,618,019 | -8,576,321 | -60,034,247 |
