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 254,024,225, 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 | 254,024,225 | |
| -1 | -254,024,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 254,024,225.
Example:
1 x 254,024,225 = 254,024,225
and
-1 x -254,024,225 = 254,024,225
Notice both answers equal 254,024,225
With that explanation out of the way, let's continue. Next, we take the number 254,024,225 and divide it by 2:
254,024,225 ÷ 2 = 127,012,112.5
If the quotient is a whole number, then 2 and 127,012,112.5 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 | 254,024,225 | |
| -1 | -254,024,225 |
Now, we try dividing 254,024,225 by 3:
254,024,225 ÷ 3 = 84,674,741.6667
If the quotient is a whole number, then 3 and 84,674,741.6667 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 | 254,024,225 | |
| -1 | -254,024,225 |
Let's try dividing by 4:
254,024,225 ÷ 4 = 63,506,056.25
If the quotient is a whole number, then 4 and 63,506,056.25 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 | 254,024,225 | |
| -1 | 254,024,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 25 | 35 | 65 | 91 | 175 | 325 | 455 | 2,275 | 111,659 | 558,295 | 781,613 | 1,451,567 | 2,791,475 | 3,908,065 | 7,257,835 | 10,160,969 | 19,540,325 | 36,289,175 | 50,804,845 | 254,024,225 |
| -1 | -5 | -7 | -13 | -25 | -35 | -65 | -91 | -175 | -325 | -455 | -2,275 | -111,659 | -558,295 | -781,613 | -1,451,567 | -2,791,475 | -3,908,065 | -7,257,835 | -10,160,969 | -19,540,325 | -36,289,175 | -50,804,845 | -254,024,225 |
