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 62,612,305, 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 | 62,612,305 | |
| -1 | -62,612,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,612,305.
Example:
1 x 62,612,305 = 62,612,305
and
-1 x -62,612,305 = 62,612,305
Notice both answers equal 62,612,305
With that explanation out of the way, let's continue. Next, we take the number 62,612,305 and divide it by 2:
62,612,305 ÷ 2 = 31,306,152.5
If the quotient is a whole number, then 2 and 31,306,152.5 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 | 62,612,305 | |
| -1 | -62,612,305 |
Now, we try dividing 62,612,305 by 3:
62,612,305 ÷ 3 = 20,870,768.3333
If the quotient is a whole number, then 3 and 20,870,768.3333 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 | 62,612,305 | |
| -1 | -62,612,305 |
Let's try dividing by 4:
62,612,305 ÷ 4 = 15,653,076.25
If the quotient is a whole number, then 4 and 15,653,076.25 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 | 62,612,305 | |
| -1 | 62,612,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 61,687 | 308,435 | 431,809 | 1,788,923 | 2,159,045 | 8,944,615 | 12,522,461 | 62,612,305 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -61,687 | -308,435 | -431,809 | -1,788,923 | -2,159,045 | -8,944,615 | -12,522,461 | -62,612,305 |
