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 63,413,545, 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 | 63,413,545 | |
| -1 | -63,413,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,413,545.
Example:
1 x 63,413,545 = 63,413,545
and
-1 x -63,413,545 = 63,413,545
Notice both answers equal 63,413,545
With that explanation out of the way, let's continue. Next, we take the number 63,413,545 and divide it by 2:
63,413,545 ÷ 2 = 31,706,772.5
If the quotient is a whole number, then 2 and 31,706,772.5 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 | 63,413,545 | |
| -1 | -63,413,545 |
Now, we try dividing 63,413,545 by 3:
63,413,545 ÷ 3 = 21,137,848.3333
If the quotient is a whole number, then 3 and 21,137,848.3333 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 | 63,413,545 | |
| -1 | -63,413,545 |
Let's try dividing by 4:
63,413,545 ÷ 4 = 15,853,386.25
If the quotient is a whole number, then 4 and 15,853,386.25 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 | 63,413,545 | |
| -1 | 63,413,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 1,235 | 51,347 | 256,735 | 667,511 | 975,593 | 3,337,555 | 4,877,965 | 12,682,709 | 63,413,545 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -1,235 | -51,347 | -256,735 | -667,511 | -975,593 | -3,337,555 | -4,877,965 | -12,682,709 | -63,413,545 |
