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 253,222,445, 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 | 253,222,445 | |
| -1 | -253,222,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 253,222,445.
Example:
1 x 253,222,445 = 253,222,445
and
-1 x -253,222,445 = 253,222,445
Notice both answers equal 253,222,445
With that explanation out of the way, let's continue. Next, we take the number 253,222,445 and divide it by 2:
253,222,445 ÷ 2 = 126,611,222.5
If the quotient is a whole number, then 2 and 126,611,222.5 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 | 253,222,445 | |
| -1 | -253,222,445 |
Now, we try dividing 253,222,445 by 3:
253,222,445 ÷ 3 = 84,407,481.6667
If the quotient is a whole number, then 3 and 84,407,481.6667 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 | 253,222,445 | |
| -1 | -253,222,445 |
Let's try dividing by 4:
253,222,445 ÷ 4 = 63,305,611.25
If the quotient is a whole number, then 4 and 63,305,611.25 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 | 253,222,445 | |
| -1 | 253,222,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 359 | 1,795 | 2,513 | 2,879 | 12,565 | 14,395 | 17,591 | 20,153 | 87,955 | 100,765 | 141,071 | 705,355 | 1,033,561 | 5,167,805 | 7,234,927 | 36,174,635 | 50,644,489 | 253,222,445 |
| -1 | -5 | -7 | -35 | -49 | -245 | -359 | -1,795 | -2,513 | -2,879 | -12,565 | -14,395 | -17,591 | -20,153 | -87,955 | -100,765 | -141,071 | -705,355 | -1,033,561 | -5,167,805 | -7,234,927 | -36,174,635 | -50,644,489 | -253,222,445 |
