Q2 C of 42 Page 136

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

5a5b, 15ab2c, 25a2b2c2


factors of 5a5b=5×a×a×a×a×a×b

Factors of 15ab2c=3×5×a×b×b×c


Factors of 25a2b2c2=5×5×a×a×b×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 5a5b, 15ab2c, 25a2b2c2=75a5b2c2
