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 119,228,525, 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 | 119,228,525 | |
| -1 | -119,228,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 119,228,525.
Example:
1 x 119,228,525 = 119,228,525
and
-1 x -119,228,525 = 119,228,525
Notice both answers equal 119,228,525
With that explanation out of the way, let's continue. Next, we take the number 119,228,525 and divide it by 2:
119,228,525 ÷ 2 = 59,614,262.5
If the quotient is a whole number, then 2 and 59,614,262.5 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 | 119,228,525 | |
| -1 | -119,228,525 |
Now, we try dividing 119,228,525 by 3:
119,228,525 ÷ 3 = 39,742,841.6667
If the quotient is a whole number, then 3 and 39,742,841.6667 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 | 119,228,525 | |
| -1 | -119,228,525 |
Let's try dividing by 4:
119,228,525 ÷ 4 = 29,807,131.25
If the quotient is a whole number, then 4 and 29,807,131.25 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 | 119,228,525 | |
| -1 | 119,228,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 71 | 325 | 355 | 923 | 1,775 | 4,615 | 5,167 | 23,075 | 25,835 | 67,171 | 129,175 | 335,855 | 366,857 | 1,679,275 | 1,834,285 | 4,769,141 | 9,171,425 | 23,845,705 | 119,228,525 |
| -1 | -5 | -13 | -25 | -65 | -71 | -325 | -355 | -923 | -1,775 | -4,615 | -5,167 | -23,075 | -25,835 | -67,171 | -129,175 | -335,855 | -366,857 | -1,679,275 | -1,834,285 | -4,769,141 | -9,171,425 | -23,845,705 | -119,228,525 |
