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

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

(ii) 4u

(iii) (4u

(iv) m

(v) k

**2. Find the highest
common factor (H.C.F.) and lowest common multiple (L.C.M.) of the three
polynomials:**

(ii) a

(iii) t

(iv) p

(v) d

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

**Answers:**

**1. **(i) H.C.F =
a(a + 3)

L.C.M. = a(a – 1) (a + 3) (2a – 1)

(ii) H.C.F = 2u – 3v

L.C.M. = u(2u + 3v)(2u – 3v)

(iii) H.C.F = 2u + 5v

L.C.M. = 3u(2u + 5v) (2u – 5v)

(iv) H.C.F = m + 4

L.C.M. = (m + 4) (m + 5) (m + 9)

(v) H.C.F = k + 5

L.C.M. = (k + 5) (k – 3) (k + 1/5)

**2. **(i) H.C.F = 3m
- n

(ii) H.C.F = a - 2

L.C.M. = (a + 1)(iii) H.C.F = 1

L.C.M. = (t + 4) (t + 1) (t - 1)

(iv) H.C.F = p + 6

L.C.M. = (p + 2) (p + 6) (p + 9) (p - 4)

(v) H.C.F = d + 8

L.C.M. = d(d + 8) (d + 7) (d - 3)

**3. **(kx + y) (kx – y) (ky + x)

**4.** pq(p – m) (q –
n) (q – 2n)
