Practice the worksheet on L.C.M. of polynomials. The questions are based on finding the lowest common multiple of two or more polynomials.

We know, to find the lowest common multiple (L.C.M.) of two or more than two polynomials is the polynomial of lowest measures (or dimensions) which is divisible by each of the polynomials without remainder.

It will be easy to pick out the common multiples if the polynomials are arranged as follows;

Therefore the L.C.M. of 3m

**1. Find the lowest
common multiple (L.C.M.) of the two polynomials:**

(ii) n

(iii) 3k

(iv) 21p

(v) p

(vi) x

(vii) 4p

(viii) 6k

(ix) a

(x) d

**2. Find the lowest
common multiple (L.C.M.) of the three polynomials:**

(ii) 3n

(iii) (2x^2 – 3xy)

(iv) a

(v) a

Answers for the worksheet on L.C.M. of polynomials are given below to check the exact answers of the above questions.

**Answers:**

**1.** (i) m(1 + m)

(iii) 12k

(iv) 21p

(v) p(p + 1) (p – 1)

(vi) xy(x + y)

(vii) pq(2p + 1) (2p – 1)

(viii) 6k(3k – 1)

(ix) a(a + 1) (a + 2)

(x) (d + 1) (d – 1) (d – 2)

**2. **(i) (a - 3) (a
– 1) (a + 2)

(ii) (n + 2) (n – 2) (3n – 7)

(iii) 8x(iv) (a + 5) (a – 4) (a – 6)

(v) a
