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 131,422,525, 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 | 131,422,525 | |
| -1 | -131,422,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 131,422,525.
Example:
1 x 131,422,525 = 131,422,525
and
-1 x -131,422,525 = 131,422,525
Notice both answers equal 131,422,525
With that explanation out of the way, let's continue. Next, we take the number 131,422,525 and divide it by 2:
131,422,525 ÷ 2 = 65,711,262.5
If the quotient is a whole number, then 2 and 65,711,262.5 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 | 131,422,525 | |
| -1 | -131,422,525 |
Now, we try dividing 131,422,525 by 3:
131,422,525 ÷ 3 = 43,807,508.3333
If the quotient is a whole number, then 3 and 43,807,508.3333 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 | 131,422,525 | |
| -1 | -131,422,525 |
Let's try dividing by 4:
131,422,525 ÷ 4 = 32,855,631.25
If the quotient is a whole number, then 4 and 32,855,631.25 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 | 131,422,525 | |
| -1 | 131,422,525 |
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 | 21,283 | 106,415 | 276,679 | 404,377 | 532,075 | 1,383,395 | 2,021,885 | 5,256,901 | 6,916,975 | 10,109,425 | 26,284,505 | 131,422,525 |
| -1 | -5 | -13 | -19 | -25 | -65 | -95 | -247 | -325 | -475 | -1,235 | -6,175 | -21,283 | -106,415 | -276,679 | -404,377 | -532,075 | -1,383,395 | -2,021,885 | -5,256,901 | -6,916,975 | -10,109,425 | -26,284,505 | -131,422,525 |
