LOWEST COMMON MULTIPLE

 L.C.M. stands for Lowest Common.LCMSo let us first discuss about what are multiples of the given number.Multiple: The number obtained by multiplying the given number is called the multiple of given number.For example: 2 × 1 = 2, 2 × 2 = 4, 2 × 3 = 6, etc. therefore 2, 4, 6, 8, etc. are the multiples...

VARIOUS TYPES OF NUMBERS

NUMBER SYSTEMNatural numbers: Counting numbers are called natural number.Thus, 1, 2, 3, 4, ...... are all natural number.Whole numbers: All counting numbers, together with 0, form the set of whole numbers. Thus, 0, 1, 2, 3, 4, ..... are all whole numbers.Integers: All counting numbers, zero and...

What are irrationals?

Irrational numbers A number that can not be written in the form p/q, where p and q are integers and q is non zero. So we can say a number which is not rational is irrational. Thus, √2, √5, π, etc. are such examples of irrational numbers.In the view of decimal expansionAs we  know the decimal...
