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 65,862,731, 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 | 65,862,731 | |
| -1 | -65,862,731 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,862,731.
Example:
1 x 65,862,731 = 65,862,731
and
-1 x -65,862,731 = 65,862,731
Notice both answers equal 65,862,731
With that explanation out of the way, let's continue. Next, we take the number 65,862,731 and divide it by 2:
65,862,731 ÷ 2 = 32,931,365.5
If the quotient is a whole number, then 2 and 32,931,365.5 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 | 65,862,731 | |
| -1 | -65,862,731 |
Now, we try dividing 65,862,731 by 3:
65,862,731 ÷ 3 = 21,954,243.6667
If the quotient is a whole number, then 3 and 21,954,243.6667 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 | 65,862,731 | |
| -1 | -65,862,731 |
Let's try dividing by 4:
65,862,731 ÷ 4 = 16,465,682.75
If the quotient is a whole number, then 4 and 16,465,682.75 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 | 65,862,731 | |
| -1 | 65,862,731 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 253 | 439 | 593 | 4,829 | 6,523 | 10,097 | 13,639 | 111,067 | 150,029 | 260,327 | 2,863,597 | 5,987,521 | 65,862,731 |
| -1 | -11 | -23 | -253 | -439 | -593 | -4,829 | -6,523 | -10,097 | -13,639 | -111,067 | -150,029 | -260,327 | -2,863,597 | -5,987,521 | -65,862,731 |
