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.)
