#### Question 1. Here are two different factor trees of the number 90. Write the missing numbers:

(i) …..

(ii) ….

(i)

Factor : 90 = 2 x 5 x 3 x 3

(ii)

Factor : 90 = 5 x 3 x 3 x 2

#### Question 2. Find the prime factorization of the following numbers:

(i) 72
(ii) 172
(iii) 450
(iv) 980
(v) 8712
(vi) 13500

(i) 72

Prime factorization of 72 = 2 x 2 x 2 x 3 x 3

(ii) 172

Prime factorization of 172 = 2 x 2 x 43

(iii) 450

Prime factorization of 450 = 2 x 3 x 3 x 5 x 5

(iv) 980

Prime factorization of 980 = 2 x 2 x 5 x 7 x 7

(v) 8712

Prime factorization of 8712 = 2 x 2 x 2 x 3 x 3 x 11 x 11

(vi) 13500

Prime factorization of 13500 = 2 x 2 x 3 x 3 x 3 x 5 x 5 x 5

#### Question 3 . Write the smallest and the greatest three digit numbers and express them as the product of prime.

Smallest three digit number = 100

so, 100 = 2 x 2 x 5 x 5
