Here is the solution for Telangana Class 10th SCERT Mathematics, Chapter number 1, Exercise 1.2 question number 1 which is **Express Each of the following numbers as a product of it's prime factors.**

**Telangana SCERT Class 10, Exercise 1.2 Question number 1 with all bits.**

**1) Express Each of the following numbers as a product of it's prime factors**

**i) 140**

**Solution: LCM of 140,**

= 140/2

= 70/2

= 35/5

= 7/7

= 1

(Therefore: Prime Factorization:- 140 = 2 x 2 x 7 x 5.)

**ii) 156**

**Solution: LCM of 156,**

= 156/2

= 78/2

= 39/3

= 13/13

= 1

(Therefore: Prime Factorization:- 156 = 2 x 2 x 3 x 13.)

**iii) 3825**

**Solution: LCM of 3825,**

= 3825/5

= 765/5

= 153/3

= 51/3

= 17/17

= 1

(Therefore: Prime Factorization:- 3850 = 5 x 5 x 3 x 3 x 17.)

**iv) 5005**

**Solution: LCM of 5005,**

= 5005/5

= 1001/7

= 143/11

= 13/13

= 1

(Therefore: Prime Factorization:- 5005 = 5 x 7 x 11 x 13.)

**v) 7429**

**Solution: LCM of 7429,**

= 7429/17

= 437/19

= 23/23

= 1

(Therefore: Prime Factorization:- 7429 = 17 x 19 x 23.)
