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 102,762,863, 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 | 102,762,863 | |
| -1 | -102,762,863 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,762,863.
Example:
1 x 102,762,863 = 102,762,863
and
-1 x -102,762,863 = 102,762,863
Notice both answers equal 102,762,863
With that explanation out of the way, let's continue. Next, we take the number 102,762,863 and divide it by 2:
102,762,863 ÷ 2 = 51,381,431.5
If the quotient is a whole number, then 2 and 51,381,431.5 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 | 102,762,863 | |
| -1 | -102,762,863 |
Now, we try dividing 102,762,863 by 3:
102,762,863 ÷ 3 = 34,254,287.6667
If the quotient is a whole number, then 3 and 34,254,287.6667 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 | 102,762,863 | |
| -1 | -102,762,863 |
Let's try dividing by 4:
102,762,863 ÷ 4 = 25,690,715.75
If the quotient is a whole number, then 4 and 25,690,715.75 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 | 102,762,863 | |
| -1 | 102,762,863 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 491 | 1,031 | 3,437 | 7,217 | 14,239 | 29,899 | 99,673 | 209,293 | 506,221 | 3,543,547 | 14,680,409 | 102,762,863 |
| -1 | -7 | -29 | -203 | -491 | -1,031 | -3,437 | -7,217 | -14,239 | -29,899 | -99,673 | -209,293 | -506,221 | -3,543,547 | -14,680,409 | -102,762,863 |
