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 62,694,781, 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 | 62,694,781 | |
| -1 | -62,694,781 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,694,781.
Example:
1 x 62,694,781 = 62,694,781
and
-1 x -62,694,781 = 62,694,781
Notice both answers equal 62,694,781
With that explanation out of the way, let's continue. Next, we take the number 62,694,781 and divide it by 2:
62,694,781 ÷ 2 = 31,347,390.5
If the quotient is a whole number, then 2 and 31,347,390.5 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 | 62,694,781 | |
| -1 | -62,694,781 |
Now, we try dividing 62,694,781 by 3:
62,694,781 ÷ 3 = 20,898,260.3333
If the quotient is a whole number, then 3 and 20,898,260.3333 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 | 62,694,781 | |
| -1 | -62,694,781 |
Let's try dividing by 4:
62,694,781 ÷ 4 = 15,673,695.25
If the quotient is a whole number, then 4 and 15,673,695.25 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 | 62,694,781 | |
| -1 | 62,694,781 |
If you did it right, you will end up with this table:
| 1 | 29 | 41 | 67 | 787 | 1,189 | 1,943 | 2,747 | 22,823 | 32,267 | 52,729 | 79,663 | 935,743 | 1,529,141 | 2,161,889 | 62,694,781 |
| -1 | -29 | -41 | -67 | -787 | -1,189 | -1,943 | -2,747 | -22,823 | -32,267 | -52,729 | -79,663 | -935,743 | -1,529,141 | -2,161,889 | -62,694,781 |
