LCM (Least Common Multiple):

LCM or Least Common Multiple is a fundamental concept in mathematics that is used to solve a wide range of problems. It is a term used to describe the smallest number that is divisible by two or more given numbers.
LCM is a useful concept in many different areas of mathematics, such as algebra, number theory, and geometry. It is commonly used in problems involving fractions and ratios, as well as in finding solutions to equations and inequalities.
    Important points about LCM (Least Common Multiple):
  1. Definition:
    LCM is the smallest positive integer that is a multiple of two or more given integers.
  2. Calculation:
    To find the LCM of two or more numbers, you can either use prime factorization method or use the division method.
  3. Prime factorization method:
    In this method, you need to find the prime factors of each of the given numbers and then multiply the highest power of each prime factor together to get the LCM.
  4. Division method:
    In this method, you need to divide the LCM by each of the given numbers and check if the remainder is zero. If the remainder is zero for all the given numbers, then the LCM is correct.
  5. Applications:
    LCM is used in many areas of mathematics, such as fractions, ratios, equations, and geometry. It is also used in finding the period of repeating decimals.
  6. Common denominator:
    LCM is used to find the common denominator when adding or subtracting fractions with different denominators.
  7. Relationship with GCD:
    LCM and GCD (Greatest Common Divisor) are related by the formula LCM(a, b) x GCD(a, b) = a x b.
  8. Not unique:
    The LCM of two or more numbers is not unique. For example, the LCM of 4 and 6 can be 12, 24, 36, and so on.
  9. Divisibility:
    If a number is divisible by two or more given numbers, then it is also divisible by their LCM.
  10. Not defined for zero:
    LCM is not defined for zero. If one or more of the given numbers is zero, then their LCM is also zero.
