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 156,641,225, 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 | 156,641,225 | |
| -1 | -156,641,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 156,641,225.
Example:
1 x 156,641,225 = 156,641,225
and
-1 x -156,641,225 = 156,641,225
Notice both answers equal 156,641,225
With that explanation out of the way, let's continue. Next, we take the number 156,641,225 and divide it by 2:
156,641,225 ÷ 2 = 78,320,612.5
If the quotient is a whole number, then 2 and 78,320,612.5 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 | 156,641,225 | |
| -1 | -156,641,225 |
Now, we try dividing 156,641,225 by 3:
156,641,225 ÷ 3 = 52,213,741.6667
If the quotient is a whole number, then 3 and 52,213,741.6667 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 | 156,641,225 | |
| -1 | -156,641,225 |
Let's try dividing by 4:
156,641,225 ÷ 4 = 39,160,306.25
If the quotient is a whole number, then 4 and 39,160,306.25 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 | 156,641,225 | |
| -1 | 156,641,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 25 | 65 | 95 | 247 | 325 | 475 | 1,235 | 6,175 | 25,367 | 126,835 | 329,771 | 481,973 | 634,175 | 1,648,855 | 2,409,865 | 6,265,649 | 8,244,275 | 12,049,325 | 31,328,245 | 156,641,225 |
| -1 | -5 | -13 | -19 | -25 | -65 | -95 | -247 | -325 | -475 | -1,235 | -6,175 | -25,367 | -126,835 | -329,771 | -481,973 | -634,175 | -1,648,855 | -2,409,865 | -6,265,649 | -8,244,275 | -12,049,325 | -31,328,245 | -156,641,225 |
