Q2 B of 42 Page 136

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

7p2q3, 35p3q, 42pq4


factors of 7p2q3=7×p×p×q×q×q

Factors of 35p3q=5×7××p×p×p×q


Factors of 42pq4=2×3×7×p×q×q×q×q


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 7p2q3, 35p3q, 42pq4 is 210p3q4
