Question

find the LCM of √3 and √6​

Answer 1

√2 and √3 don't have any LCM.

LCM : Lowest Common Multiple.

LCM is the lowest number in the set of integral multiples of the operands.

Multiples of √2 : √2, 2√2, 3√2, 4√2, 5√2, 6√2, 7√2, 8√2, 9√2, 10√2, .....

Multiples of √3 : √3, 2√3, 3√3, 4√3, 5√3, 6√2, 7√2, 8√2, 9√2, 10√2, .....

Since √2 and √3 don't have any multiple in common, they don't have any LCM. That's why irrational numbers don't have the concept of LCM.

Hope it helps :-)
