Answer :
Final answer:
The LCM of 147 and 441 is found by factoring both numbers into their prime factors and taking the highest power of all primes that appear, resulting in an LCM of 441. Option C.
Explanation:
The Least Common Multiple (LCM) of 147 and 441. To find the LCM, firstly, we need to factor each number to its prime factors. 147 is factored into 3 × 7 × 7, and 441 is factored into 3 × 3 × 7 × 7. The LCM is then found by taking the highest power of all primes that appear in the factorization of both numbers, which gives us 3² (or 9) × 7 × 7 = 441. Therefore, the answer is C) 441.
