Find LCM of 24, 36, 108, 192
Given:
Given numbers are 24, 36, 108 and 192.
To do:
We have to find the LCM of the given integers.
Solution:
Writing the numbers as a product of their prime factors:
Prime factorisation of 24:
- $2\ \times\ 2\ \times\ 2\ \times\ 3\ =\ 2^3\ \times\ 3^1$
Prime factorisation of 36:
- $2\ \times\ 2\ \times\ 2\ \times\ 3\ =\ 2^3\ \times\ 3^1$
Prime factorisation of 108:
- $2\ \times\ 2\ \times\ 3\ \times\ 3\ \times\ 3\ =\ 2^2\ \times\ 3^3$
Prime factorisation of 192:
- $2\ \times\ 2\ \times\ 2\ \times\ 2\ \times\ 2\ \times\ 2\ \times\ 3=\ 2^6\ \times\ 3^1$
Multiplying the highest power of each prime number these values together:
$2^6\ \times\ 3^3\ =64\times27$
LCM(24, 36, 108, 192) $=1728$
Therefore, LCM of 24, 36, 108, 192 is 1728.
