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 127,747,225, 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 | 127,747,225 | |
| -1 | -127,747,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 127,747,225.
Example:
1 x 127,747,225 = 127,747,225
and
-1 x -127,747,225 = 127,747,225
Notice both answers equal 127,747,225
With that explanation out of the way, let's continue. Next, we take the number 127,747,225 and divide it by 2:
127,747,225 ÷ 2 = 63,873,612.5
If the quotient is a whole number, then 2 and 63,873,612.5 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 | 127,747,225 | |
| -1 | -127,747,225 |
Now, we try dividing 127,747,225 by 3:
127,747,225 ÷ 3 = 42,582,408.3333
If the quotient is a whole number, then 3 and 42,582,408.3333 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 | 127,747,225 | |
| -1 | -127,747,225 |
Let's try dividing by 4:
127,747,225 ÷ 4 = 31,936,806.25
If the quotient is a whole number, then 4 and 31,936,806.25 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 | 127,747,225 | |
| -1 | 127,747,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 53 | 67 | 265 | 335 | 1,325 | 1,439 | 1,675 | 3,551 | 7,195 | 17,755 | 35,975 | 76,267 | 88,775 | 96,413 | 381,335 | 482,065 | 1,906,675 | 2,410,325 | 5,109,889 | 25,549,445 | 127,747,225 |
| -1 | -5 | -25 | -53 | -67 | -265 | -335 | -1,325 | -1,439 | -1,675 | -3,551 | -7,195 | -17,755 | -35,975 | -76,267 | -88,775 | -96,413 | -381,335 | -482,065 | -1,906,675 | -2,410,325 | -5,109,889 | -25,549,445 | -127,747,225 |
