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 63,216,545, 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 | 63,216,545 | |
| -1 | -63,216,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,216,545.
Example:
1 x 63,216,545 = 63,216,545
and
-1 x -63,216,545 = 63,216,545
Notice both answers equal 63,216,545
With that explanation out of the way, let's continue. Next, we take the number 63,216,545 and divide it by 2:
63,216,545 ÷ 2 = 31,608,272.5
If the quotient is a whole number, then 2 and 31,608,272.5 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 | 63,216,545 | |
| -1 | -63,216,545 |
Now, we try dividing 63,216,545 by 3:
63,216,545 ÷ 3 = 21,072,181.6667
If the quotient is a whole number, then 3 and 21,072,181.6667 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 | 63,216,545 | |
| -1 | -63,216,545 |
Let's try dividing by 4:
63,216,545 ÷ 4 = 15,804,136.25
If the quotient is a whole number, then 4 and 15,804,136.25 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 | 63,216,545 | |
| -1 | 63,216,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 53 | 265 | 371 | 643 | 1,855 | 2,809 | 3,215 | 4,501 | 14,045 | 19,663 | 22,505 | 34,079 | 98,315 | 170,395 | 238,553 | 1,192,765 | 1,806,187 | 9,030,935 | 12,643,309 | 63,216,545 |
| -1 | -5 | -7 | -35 | -53 | -265 | -371 | -643 | -1,855 | -2,809 | -3,215 | -4,501 | -14,045 | -19,663 | -22,505 | -34,079 | -98,315 | -170,395 | -238,553 | -1,192,765 | -1,806,187 | -9,030,935 | -12,643,309 | -63,216,545 |
