Q. 2 D4.3( 6 Votes )

Let’s find the L.C.M. of the following algebraic expressions:

11a²bc², 33a²b²c, 55a²bc²

Class 8th West Bengal - Mathematics 14. HCF and LCM of Algebraic Expression

Answer :

Factors of 11a²bc²=11×a×a×b×c×c

Factors of 33a²b²c=3×11×a×a×b×b×c

Factors of 55a²bc²=5×11×a×a×b×c×c

LCM is the lowest common multiple, which is the product of all the common factors taken once and the remaining factors as it is.

∴the LCM of 11a²bc², 33a²b²c, 55a²bc²=165 a²b²c²
