Answer:
<h2>its lcm(4, 2) = 4 </h2>
Prime factorization of 2 and 4 is (2) = 21 and (2 × 2) = 22 respectively. LCM of 2 and 4 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 22 = 4.
Hence, the LCM of 2 and 4 by prime factorization is 4.
To calculate the LCM of 2 and 4 by listing out the common multiples, we can follow the given below steps:
Step 1: List a few multiples of 2 (2, 4, 6, 8, 10, . . . ) and 4 (4, 8, 12, 16, . . . . )
Step 2: The common multiples from the multiples of 2 and 4 are 4, 8, . . .
Step 3: The smallest common multiple of 2 and 4 is 4.
∴ The least common multiple of 2 and 4 = 4.
