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 130,445,525, 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 | 130,445,525 | |
| -1 | -130,445,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,445,525.
Example:
1 x 130,445,525 = 130,445,525
and
-1 x -130,445,525 = 130,445,525
Notice both answers equal 130,445,525
With that explanation out of the way, let's continue. Next, we take the number 130,445,525 and divide it by 2:
130,445,525 ÷ 2 = 65,222,762.5
If the quotient is a whole number, then 2 and 65,222,762.5 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 | 130,445,525 | |
| -1 | -130,445,525 |
Now, we try dividing 130,445,525 by 3:
130,445,525 ÷ 3 = 43,481,841.6667
If the quotient is a whole number, then 3 and 43,481,841.6667 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 | 130,445,525 | |
| -1 | -130,445,525 |
Let's try dividing by 4:
130,445,525 ÷ 4 = 32,611,381.25
If the quotient is a whole number, then 4 and 32,611,381.25 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 | 130,445,525 | |
| -1 | 130,445,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 73 | 175 | 365 | 511 | 1,825 | 2,555 | 10,211 | 12,775 | 51,055 | 71,477 | 255,275 | 357,385 | 745,403 | 1,786,925 | 3,727,015 | 5,217,821 | 18,635,075 | 26,089,105 | 130,445,525 |
| -1 | -5 | -7 | -25 | -35 | -73 | -175 | -365 | -511 | -1,825 | -2,555 | -10,211 | -12,775 | -51,055 | -71,477 | -255,275 | -357,385 | -745,403 | -1,786,925 | -3,727,015 | -5,217,821 | -18,635,075 | -26,089,105 | -130,445,525 |
