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

(p + q) (p + r), (q + r) (r + p), (r + p) (p + q)

Answer :

Factors of (p + q) (p + r)

=(p + q)×(p + r)

Factors of (q + r)(r + p)

= (q + r)×(r + p)

Factors of (r + p) (p + q)

=(r + p)×(p + 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 (p + q)(p + r), (q + r)(r + p), (r + p)(p + q) is (p + q)(q + r)(p + r)
