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 102,523,525, 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 | 102,523,525 | |
| -1 | -102,523,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,523,525.
Example:
1 x 102,523,525 = 102,523,525
and
-1 x -102,523,525 = 102,523,525
Notice both answers equal 102,523,525
With that explanation out of the way, let's continue. Next, we take the number 102,523,525 and divide it by 2:
102,523,525 ÷ 2 = 51,261,762.5
If the quotient is a whole number, then 2 and 51,261,762.5 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 | 102,523,525 | |
| -1 | -102,523,525 |
Now, we try dividing 102,523,525 by 3:
102,523,525 ÷ 3 = 34,174,508.3333
If the quotient is a whole number, then 3 and 34,174,508.3333 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 | 102,523,525 | |
| -1 | -102,523,525 |
Let's try dividing by 4:
102,523,525 ÷ 4 = 25,630,881.25
If the quotient is a whole number, then 4 and 25,630,881.25 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 | 102,523,525 | |
| -1 | 102,523,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 25 | 65 | 95 | 247 | 325 | 475 | 1,235 | 6,175 | 16,603 | 83,015 | 215,839 | 315,457 | 415,075 | 1,079,195 | 1,577,285 | 4,100,941 | 5,395,975 | 7,886,425 | 20,504,705 | 102,523,525 |
| -1 | -5 | -13 | -19 | -25 | -65 | -95 | -247 | -325 | -475 | -1,235 | -6,175 | -16,603 | -83,015 | -215,839 | -315,457 | -415,075 | -1,079,195 | -1,577,285 | -4,100,941 | -5,395,975 | -7,886,425 | -20,504,705 | -102,523,525 |
