Question

find the least common multiple (lcm) of 4 and 14.

Explanation:

Step1: Prime factorize 4

$4 = 2^2$

Step2: Prime factorize 14

$14 = 2 \times 7$

Step3: Take highest powers of primes

$\text{LCM} = 2^2 \times 7$

Step4: Calculate the product

$2^2 \times 7 = 4 \times 7 = 28$

Answer:

28
