👉 Undemolished in mathematics refers to a number or quantity that is not divisible by any prime numbers. This means it has no factors other than 1 and itself, making it unattainable through arithmetic operations like addition, subtraction, multiplication, division, etc., due to the lack of divisors. For example, 5 cannot be divided evenly into 4 because 2 is a factor of both 4 and 5.
