Question

what is the LCM of 18 and 72​

Answer 1

Answer:

LCM = 72

Step-by-step explanation:

The LCM(a. b) is calculated by finding the prime factorization of both a and b then taking the product of the sets of primes with the highest exponent value among a and b. and here a and b are 18 and 72 respectively.

• Prime factorization of 18 = 2 x 3 x 3  = 2¹ x 3²
• Prime factorization of 72 = 2 x 2 x 2 x 3 x 3  = 2³ x 3²
• Using the set of prime numbers from each set with the highest exponent value we take 2³ x 3² = 72

• Therefore LCM(18, 72) = 72.
