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 63,637,525, 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 | 63,637,525 | |
| -1 | -63,637,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,637,525.
Example:
1 x 63,637,525 = 63,637,525
and
-1 x -63,637,525 = 63,637,525
Notice both answers equal 63,637,525
With that explanation out of the way, let's continue. Next, we take the number 63,637,525 and divide it by 2:
63,637,525 ÷ 2 = 31,818,762.5
If the quotient is a whole number, then 2 and 31,818,762.5 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 | 63,637,525 | |
| -1 | -63,637,525 |
Now, we try dividing 63,637,525 by 3:
63,637,525 ÷ 3 = 21,212,508.3333
If the quotient is a whole number, then 3 and 21,212,508.3333 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 | 63,637,525 | |
| -1 | -63,637,525 |
Let's try dividing by 4:
63,637,525 ÷ 4 = 15,909,381.25
If the quotient is a whole number, then 4 and 15,909,381.25 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 | 63,637,525 | |
| -1 | 63,637,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 51,949 | 259,745 | 363,643 | 1,298,725 | 1,818,215 | 2,545,501 | 9,091,075 | 12,727,505 | 63,637,525 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -51,949 | -259,745 | -363,643 | -1,298,725 | -1,818,215 | -2,545,501 | -9,091,075 | -12,727,505 | -63,637,525 |
