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 62,010,221, 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 | 62,010,221 | |
| -1 | -62,010,221 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,010,221.
Example:
1 x 62,010,221 = 62,010,221
and
-1 x -62,010,221 = 62,010,221
Notice both answers equal 62,010,221
With that explanation out of the way, let's continue. Next, we take the number 62,010,221 and divide it by 2:
62,010,221 ÷ 2 = 31,005,110.5
If the quotient is a whole number, then 2 and 31,005,110.5 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 | 62,010,221 | |
| -1 | -62,010,221 |
Now, we try dividing 62,010,221 by 3:
62,010,221 ÷ 3 = 20,670,073.6667
If the quotient is a whole number, then 3 and 20,670,073.6667 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 | 62,010,221 | |
| -1 | -62,010,221 |
Let's try dividing by 4:
62,010,221 ÷ 4 = 15,502,555.25
If the quotient is a whole number, then 4 and 15,502,555.25 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 | 62,010,221 | |
| -1 | 62,010,221 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 61 | 91 | 427 | 793 | 5,551 | 11,171 | 78,197 | 145,223 | 681,431 | 1,016,561 | 4,770,017 | 8,858,603 | 62,010,221 |
| -1 | -7 | -13 | -61 | -91 | -427 | -793 | -5,551 | -11,171 | -78,197 | -145,223 | -681,431 | -1,016,561 | -4,770,017 | -8,858,603 | -62,010,221 |
