Frequently asked questions

The Number System is the classification and study of different types of numbers and their properties. It includes natural numbers, whole numbers, integers, rational numbers, irrational numbers, real numbers, prime numbers, and composite numbers.

No. The number 1 is neither prime nor composite because it has exactly one positive factor. A prime number must have exactly two positive factors: 1 and itself.

HCF is the greatest positive number that divides two or more numbers exactly. LCM is the smallest positive number that is a multiple of two or more numbers.

A remainder is the amount left after an integer division that does not divide evenly. For example, dividing 17 by 5 gives a quotient of 3 and a remainder of 2.

Number-system concepts are used in many quantitative aptitude questions involving divisibility, factors, HCF, LCM, remainders, powers, fractions, and numerical patterns. Understanding these concepts also helps solve other mathematical topics more efficiently.
