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 63,411,325, 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 | 63,411,325 | |
| -1 | -63,411,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,411,325.
Example:
1 x 63,411,325 = 63,411,325
and
-1 x -63,411,325 = 63,411,325
Notice both answers equal 63,411,325
With that explanation out of the way, let's continue. Next, we take the number 63,411,325 and divide it by 2:
63,411,325 ÷ 2 = 31,705,662.5
If the quotient is a whole number, then 2 and 31,705,662.5 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 | 63,411,325 | |
| -1 | -63,411,325 |
Now, we try dividing 63,411,325 by 3:
63,411,325 ÷ 3 = 21,137,108.3333
If the quotient is a whole number, then 3 and 21,137,108.3333 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 | 63,411,325 | |
| -1 | -63,411,325 |
Let's try dividing by 4:
63,411,325 ÷ 4 = 15,852,831.25
If the quotient is a whole number, then 4 and 15,852,831.25 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 | 63,411,325 | |
| -1 | 63,411,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 79 | 97 | 331 | 395 | 485 | 1,655 | 1,975 | 2,425 | 7,663 | 8,275 | 26,149 | 32,107 | 38,315 | 130,745 | 160,535 | 191,575 | 653,725 | 802,675 | 2,536,453 | 12,682,265 | 63,411,325 |
| -1 | -5 | -25 | -79 | -97 | -331 | -395 | -485 | -1,655 | -1,975 | -2,425 | -7,663 | -8,275 | -26,149 | -32,107 | -38,315 | -130,745 | -160,535 | -191,575 | -653,725 | -802,675 | -2,536,453 | -12,682,265 | -63,411,325 |
