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 253,351,525, 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 | 253,351,525 | |
| -1 | -253,351,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 253,351,525.
Example:
1 x 253,351,525 = 253,351,525
and
-1 x -253,351,525 = 253,351,525
Notice both answers equal 253,351,525
With that explanation out of the way, let's continue. Next, we take the number 253,351,525 and divide it by 2:
253,351,525 ÷ 2 = 126,675,762.5
If the quotient is a whole number, then 2 and 126,675,762.5 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 | 253,351,525 | |
| -1 | -253,351,525 |
Now, we try dividing 253,351,525 by 3:
253,351,525 ÷ 3 = 84,450,508.3333
If the quotient is a whole number, then 3 and 84,450,508.3333 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 | 253,351,525 | |
| -1 | -253,351,525 |
Let's try dividing by 4:
253,351,525 ÷ 4 = 63,337,881.25
If the quotient is a whole number, then 4 and 63,337,881.25 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 | 253,351,525 | |
| -1 | 253,351,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 167 | 175 | 835 | 1,169 | 4,175 | 5,845 | 8,669 | 29,225 | 43,345 | 60,683 | 216,725 | 303,415 | 1,447,723 | 1,517,075 | 7,238,615 | 10,134,061 | 36,193,075 | 50,670,305 | 253,351,525 |
| -1 | -5 | -7 | -25 | -35 | -167 | -175 | -835 | -1,169 | -4,175 | -5,845 | -8,669 | -29,225 | -43,345 | -60,683 | -216,725 | -303,415 | -1,447,723 | -1,517,075 | -7,238,615 | -10,134,061 | -36,193,075 | -50,670,305 | -253,351,525 |
