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 62,567,791, 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 | 62,567,791 | |
| -1 | -62,567,791 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,567,791.
Example:
1 x 62,567,791 = 62,567,791
and
-1 x -62,567,791 = 62,567,791
Notice both answers equal 62,567,791
With that explanation out of the way, let's continue. Next, we take the number 62,567,791 and divide it by 2:
62,567,791 ÷ 2 = 31,283,895.5
If the quotient is a whole number, then 2 and 31,283,895.5 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 | 62,567,791 | |
| -1 | -62,567,791 |
Now, we try dividing 62,567,791 by 3:
62,567,791 ÷ 3 = 20,855,930.3333
If the quotient is a whole number, then 3 and 20,855,930.3333 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 | 62,567,791 | |
| -1 | -62,567,791 |
Let's try dividing by 4:
62,567,791 ÷ 4 = 15,641,947.75
If the quotient is a whole number, then 4 and 15,641,947.75 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 | 62,567,791 | |
| -1 | 62,567,791 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 197 | 2,167 | 2,221 | 2,561 | 24,431 | 28,171 | 28,873 | 317,603 | 437,537 | 4,812,907 | 5,687,981 | 62,567,791 |
| -1 | -11 | -13 | -143 | -197 | -2,167 | -2,221 | -2,561 | -24,431 | -28,171 | -28,873 | -317,603 | -437,537 | -4,812,907 | -5,687,981 | -62,567,791 |
