In multiplication there is multiplication of 5 and 2 =10 means after whole multiplication there will be 0 at once or unit place.
After we add 5 in product there will be 5 at once or unit place.
We know that if there is 5 in the unit place then it will be divided by 5
And prime no are only divided by 1 and own
But this product is divided by 5 so it is always composite no

A composite number is a number that can be divided evenly by more numbers than 1 and itself. ... Since 123,456,789 cannot be divided by just 1 and 123,456,789, it is a composite number.
