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 102,151,283, 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 | 102,151,283 | |
| -1 | -102,151,283 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,151,283.
Example:
1 x 102,151,283 = 102,151,283
and
-1 x -102,151,283 = 102,151,283
Notice both answers equal 102,151,283
With that explanation out of the way, let's continue. Next, we take the number 102,151,283 and divide it by 2:
102,151,283 ÷ 2 = 51,075,641.5
If the quotient is a whole number, then 2 and 51,075,641.5 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 | 102,151,283 | |
| -1 | -102,151,283 |
Now, we try dividing 102,151,283 by 3:
102,151,283 ÷ 3 = 34,050,427.6667
If the quotient is a whole number, then 3 and 34,050,427.6667 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 | 102,151,283 | |
| -1 | -102,151,283 |
Let's try dividing by 4:
102,151,283 ÷ 4 = 25,537,820.75
If the quotient is a whole number, then 4 and 25,537,820.75 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 | 102,151,283 | |
| -1 | 102,151,283 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 563 | 821 | 7,319 | 9,571 | 10,673 | 13,957 | 124,423 | 181,441 | 462,223 | 6,008,899 | 7,857,791 | 102,151,283 |
| -1 | -13 | -17 | -221 | -563 | -821 | -7,319 | -9,571 | -10,673 | -13,957 | -124,423 | -181,441 | -462,223 | -6,008,899 | -7,857,791 | -102,151,283 |
