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 62,770,645, 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 | 62,770,645 | |
| -1 | -62,770,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,770,645.
Example:
1 x 62,770,645 = 62,770,645
and
-1 x -62,770,645 = 62,770,645
Notice both answers equal 62,770,645
With that explanation out of the way, let's continue. Next, we take the number 62,770,645 and divide it by 2:
62,770,645 ÷ 2 = 31,385,322.5
If the quotient is a whole number, then 2 and 31,385,322.5 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 | 62,770,645 | |
| -1 | -62,770,645 |
Now, we try dividing 62,770,645 by 3:
62,770,645 ÷ 3 = 20,923,548.3333
If the quotient is a whole number, then 3 and 20,923,548.3333 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 | 62,770,645 | |
| -1 | -62,770,645 |
Let's try dividing by 4:
62,770,645 ÷ 4 = 15,692,661.25
If the quotient is a whole number, then 4 and 15,692,661.25 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 | 62,770,645 | |
| -1 | 62,770,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 61,843 | 309,215 | 432,901 | 1,793,447 | 2,164,505 | 8,967,235 | 12,554,129 | 62,770,645 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -61,843 | -309,215 | -432,901 | -1,793,447 | -2,164,505 | -8,967,235 | -12,554,129 | -62,770,645 |
