Practice the questions given in the worksheet on H.C.F. and
L.C.M. of monomials. The questions are based on finding the highest common
factor (H.C.F.) and lowest common multiple**
**(L.C.M.)** **of two or more monomials.

**1. Find the highest
common factor (H.C.F.) and lowest common multiple (L.C.M.) of the two
monomials:**

(ii) a

(iii) 15p

(iv) 13x

(v) 17abc

(vi) 15p

(vii) 17a

(viii) 72a

**2. Find the H.C.F.
and L.C.M. of the following three monomials:**

(i) 2xyz, 3xz and 4xyz

(ii) 2ab, 4bc and 6abc

(iii) 9pqr, 3q(iv) 3mn

(v) 11xyz

(vi) -4m

(vii) x

(viii) 3xy, 2yz and 5xyz

(ix) 20x

(x) 5ab, 9b

(xi) a

(xii) 15x
