Question

Example 19: Find the LCM of 12.15 and 16 by prime
factorisation
Solution:
The prime factorisation of 12 is 2 x 2 x 3.
The prime factorisation of 15 is 3 x 5.
The prime factorisation of 16 is 2 x 2 x 2 x 2.
The prime number 3 occurs once in the factorisation
of 12.
The prime number 5 occurs once in the factorisation
of 15.
The prime number 2 occurs four times in the
factorisation of 16.
Hence, the LCM of the numbers 12, 15 and 16 is
(2 x 2 x 2 x 2) (3) X (5) - 240.​
