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 63,619,325, 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 | 63,619,325 | |
| -1 | -63,619,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,619,325.
Example:
1 x 63,619,325 = 63,619,325
and
-1 x -63,619,325 = 63,619,325
Notice both answers equal 63,619,325
With that explanation out of the way, let's continue. Next, we take the number 63,619,325 and divide it by 2:
63,619,325 ÷ 2 = 31,809,662.5
If the quotient is a whole number, then 2 and 31,809,662.5 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 | 63,619,325 | |
| -1 | -63,619,325 |
Now, we try dividing 63,619,325 by 3:
63,619,325 ÷ 3 = 21,206,441.6667
If the quotient is a whole number, then 3 and 21,206,441.6667 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 | 63,619,325 | |
| -1 | -63,619,325 |
Let's try dividing by 4:
63,619,325 ÷ 4 = 15,904,831.25
If the quotient is a whole number, then 4 and 15,904,831.25 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 | 63,619,325 | |
| -1 | 63,619,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 175 | 275 | 385 | 1,925 | 33,049 | 165,245 | 231,343 | 363,539 | 826,225 | 1,156,715 | 1,817,695 | 2,544,773 | 5,783,575 | 9,088,475 | 12,723,865 | 63,619,325 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -175 | -275 | -385 | -1,925 | -33,049 | -165,245 | -231,343 | -363,539 | -826,225 | -1,156,715 | -1,817,695 | -2,544,773 | -5,783,575 | -9,088,475 | -12,723,865 | -63,619,325 |
