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 63,403,607, 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 | 63,403,607 | |
| -1 | -63,403,607 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,403,607.
Example:
1 x 63,403,607 = 63,403,607
and
-1 x -63,403,607 = 63,403,607
Notice both answers equal 63,403,607
With that explanation out of the way, let's continue. Next, we take the number 63,403,607 and divide it by 2:
63,403,607 ÷ 2 = 31,701,803.5
If the quotient is a whole number, then 2 and 31,701,803.5 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 | 63,403,607 | |
| -1 | -63,403,607 |
Now, we try dividing 63,403,607 by 3:
63,403,607 ÷ 3 = 21,134,535.6667
If the quotient is a whole number, then 3 and 21,134,535.6667 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 | 63,403,607 | |
| -1 | -63,403,607 |
Let's try dividing by 4:
63,403,607 ÷ 4 = 15,850,901.75
If the quotient is a whole number, then 4 and 15,850,901.75 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 | 63,403,607 | |
| -1 | 63,403,607 |
If you did it right, you will end up with this table:
| 1 | 37 | 103 | 127 | 131 | 3,811 | 4,699 | 4,847 | 13,081 | 13,493 | 16,637 | 483,997 | 499,241 | 615,569 | 1,713,611 | 63,403,607 |
| -1 | -37 | -103 | -127 | -131 | -3,811 | -4,699 | -4,847 | -13,081 | -13,493 | -16,637 | -483,997 | -499,241 | -615,569 | -1,713,611 | -63,403,607 |
