Find the LCM of the numbers 44, 126, 198, and 280.

Answer :

Final answer:

The least common multiple (LCM) of the numbers 44, 126, 198, and 280 is 27720. This is found by first identifying the prime factors of each number, and then multiplying together the highest power of these prime factors.

Explanation:

To find the least common multiple (LCM) we need to follow few steps. Firstly we will start by finding the prime factorization of each number:

  • 44 = 2 x 2 x 11
  • 126 = 2 x 3 x 3 x 7
  • 198 = 2 x 3 x 3 x 11
  • 280 = 2 x 2 x 2 x 5 x 7

Now, the LCM is found by multiplying the highest power of all primes occurring in the numbers. Here, we have the primes 2, 3, 5, 7 and 11. The highest power for 2 is 3 (from 280), for 3 is 2 (from 126 and 198), for 5 is 1 (from 280), for 7 is 1 (from 126 and 280), and for 11 is 1 (from 44 and 198).

Therefore, LCM = 2³ x 3² x 5¹x 7¹ x 11¹ = 8 x 9 x 5 x 7 x 11 = 27720.

Thus, the LCM of 44, 126, 198 and 280 is 27720.
