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 126,151,525, 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 | 126,151,525 | |
| -1 | -126,151,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 126,151,525.
Example:
1 x 126,151,525 = 126,151,525
and
-1 x -126,151,525 = 126,151,525
Notice both answers equal 126,151,525
With that explanation out of the way, let's continue. Next, we take the number 126,151,525 and divide it by 2:
126,151,525 ÷ 2 = 63,075,762.5
If the quotient is a whole number, then 2 and 63,075,762.5 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 | 126,151,525 | |
| -1 | -126,151,525 |
Now, we try dividing 126,151,525 by 3:
126,151,525 ÷ 3 = 42,050,508.3333
If the quotient is a whole number, then 3 and 42,050,508.3333 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 | 126,151,525 | |
| -1 | -126,151,525 |
Let's try dividing by 4:
126,151,525 ÷ 4 = 31,537,881.25
If the quotient is a whole number, then 4 and 31,537,881.25 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 | 126,151,525 | |
| -1 | 126,151,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 47 | 101 | 235 | 505 | 1,063 | 1,175 | 2,525 | 4,747 | 5,315 | 23,735 | 26,575 | 49,961 | 107,363 | 118,675 | 249,805 | 536,815 | 1,249,025 | 2,684,075 | 5,046,061 | 25,230,305 | 126,151,525 |
| -1 | -5 | -25 | -47 | -101 | -235 | -505 | -1,063 | -1,175 | -2,525 | -4,747 | -5,315 | -23,735 | -26,575 | -49,961 | -107,363 | -118,675 | -249,805 | -536,815 | -1,249,025 | -2,684,075 | -5,046,061 | -25,230,305 | -126,151,525 |
