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 122,542,525, 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 | 122,542,525 | |
| -1 | -122,542,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,542,525.
Example:
1 x 122,542,525 = 122,542,525
and
-1 x -122,542,525 = 122,542,525
Notice both answers equal 122,542,525
With that explanation out of the way, let's continue. Next, we take the number 122,542,525 and divide it by 2:
122,542,525 ÷ 2 = 61,271,262.5
If the quotient is a whole number, then 2 and 61,271,262.5 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 | 122,542,525 | |
| -1 | -122,542,525 |
Now, we try dividing 122,542,525 by 3:
122,542,525 ÷ 3 = 40,847,508.3333
If the quotient is a whole number, then 3 and 40,847,508.3333 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 | 122,542,525 | |
| -1 | -122,542,525 |
Let's try dividing by 4:
122,542,525 ÷ 4 = 30,635,631.25
If the quotient is a whole number, then 4 and 30,635,631.25 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 | 122,542,525 | |
| -1 | 122,542,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 97 | 175 | 485 | 679 | 2,425 | 3,395 | 7,219 | 16,975 | 36,095 | 50,533 | 180,475 | 252,665 | 700,243 | 1,263,325 | 3,501,215 | 4,901,701 | 17,506,075 | 24,508,505 | 122,542,525 |
| -1 | -5 | -7 | -25 | -35 | -97 | -175 | -485 | -679 | -2,425 | -3,395 | -7,219 | -16,975 | -36,095 | -50,533 | -180,475 | -252,665 | -700,243 | -1,263,325 | -3,501,215 | -4,901,701 | -17,506,075 | -24,508,505 | -122,542,525 |
