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 187,725,503, 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 | 187,725,503 | |
| -1 | -187,725,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 187,725,503.
Example:
1 x 187,725,503 = 187,725,503
and
-1 x -187,725,503 = 187,725,503
Notice both answers equal 187,725,503
With that explanation out of the way, let's continue. Next, we take the number 187,725,503 and divide it by 2:
187,725,503 ÷ 2 = 93,862,751.5
If the quotient is a whole number, then 2 and 93,862,751.5 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 | 187,725,503 | |
| -1 | -187,725,503 |
Now, we try dividing 187,725,503 by 3:
187,725,503 ÷ 3 = 62,575,167.6667
If the quotient is a whole number, then 3 and 62,575,167.6667 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 | 187,725,503 | |
| -1 | -187,725,503 |
Let's try dividing by 4:
187,725,503 ÷ 4 = 46,931,375.75
If the quotient is a whole number, then 4 and 46,931,375.75 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 | 187,725,503 | |
| -1 | 187,725,503 |
If you did it right, you will end up with this table:
| 1 | 7 | 193 | 283 | 491 | 1,351 | 1,981 | 3,437 | 54,619 | 94,763 | 138,953 | 382,333 | 663,341 | 972,671 | 26,817,929 | 187,725,503 |
| -1 | -7 | -193 | -283 | -491 | -1,351 | -1,981 | -3,437 | -54,619 | -94,763 | -138,953 | -382,333 | -663,341 | -972,671 | -26,817,929 | -187,725,503 |
