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 125,422,865, 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 | 125,422,865 | |
| -1 | -125,422,865 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,422,865.
Example:
1 x 125,422,865 = 125,422,865
and
-1 x -125,422,865 = 125,422,865
Notice both answers equal 125,422,865
With that explanation out of the way, let's continue. Next, we take the number 125,422,865 and divide it by 2:
125,422,865 ÷ 2 = 62,711,432.5
If the quotient is a whole number, then 2 and 62,711,432.5 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 | 125,422,865 | |
| -1 | -125,422,865 |
Now, we try dividing 125,422,865 by 3:
125,422,865 ÷ 3 = 41,807,621.6667
If the quotient is a whole number, then 3 and 41,807,621.6667 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 | 125,422,865 | |
| -1 | -125,422,865 |
Let's try dividing by 4:
125,422,865 ÷ 4 = 31,355,716.25
If the quotient is a whole number, then 4 and 31,355,716.25 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 | 125,422,865 | |
| -1 | 125,422,865 |
If you did it right, you will end up with this table:
| 1 | 5 | 151 | 271 | 613 | 755 | 1,355 | 3,065 | 40,921 | 92,563 | 166,123 | 204,605 | 462,815 | 830,615 | 25,084,573 | 125,422,865 |
| -1 | -5 | -151 | -271 | -613 | -755 | -1,355 | -3,065 | -40,921 | -92,563 | -166,123 | -204,605 | -462,815 | -830,615 | -25,084,573 | -125,422,865 |
