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 62,771,885, 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 | 62,771,885 | |
| -1 | -62,771,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,771,885.
Example:
1 x 62,771,885 = 62,771,885
and
-1 x -62,771,885 = 62,771,885
Notice both answers equal 62,771,885
With that explanation out of the way, let's continue. Next, we take the number 62,771,885 and divide it by 2:
62,771,885 ÷ 2 = 31,385,942.5
If the quotient is a whole number, then 2 and 31,385,942.5 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 | 62,771,885 | |
| -1 | -62,771,885 |
Now, we try dividing 62,771,885 by 3:
62,771,885 ÷ 3 = 20,923,961.6667
If the quotient is a whole number, then 3 and 20,923,961.6667 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 | 62,771,885 | |
| -1 | -62,771,885 |
Let's try dividing by 4:
62,771,885 ÷ 4 = 15,692,971.25
If the quotient is a whole number, then 4 and 15,692,971.25 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 | 62,771,885 | |
| -1 | 62,771,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 503 | 2,269 | 2,515 | 5,533 | 11,345 | 24,959 | 27,665 | 124,795 | 1,141,307 | 5,706,535 | 12,554,377 | 62,771,885 |
| -1 | -5 | -11 | -55 | -503 | -2,269 | -2,515 | -5,533 | -11,345 | -24,959 | -27,665 | -124,795 | -1,141,307 | -5,706,535 | -12,554,377 | -62,771,885 |
