Example 2 : find the lcm and hcf of 6 and 20 by the prime factorisation method. solution : we have : 6 = 21 × 31 and 20 = 2 × 2 × 5 = 22 × 51. you can find hcf(6, 20) = 2 and lcm(6, 20) = 2 × 2 × 3 × 5 = 60, as done in your earlier classes. note that hcf(6, 20) = 21 = product of the smallest power of each common prime factor in the numbers.
Rd Sharma Solutions For Class 10 Maths Chapter 1 Real Numbers Express each number as a product of its prime factors:(i) 140(ii) 156(iii) 3825(iv) 5005(v) 74292. find the lcm and hcf of the following pairs cbse exam, class 10. Real numbers class 10 important questions short answer i (2 marks) question 6. hcf and lcm of two numbers is 9 and 459 respectively. if one of the numbers is 27, find the other number. (2012) solution: we know, 1st number × 2nd number = hcf × lcm ⇒ 27 × 2nd number = 9 × 459 ⇒ 2nd number = \(\frac { 9\times 459 }{ 27 }\) = 153. Ex 1.1, 2 find the lcm and hcf of the following pairs of integers and verify that lcm × hcf = product of the two numbers. 26 and 91 finding hcf ∴ h.c.f = 13 finding l.c.m l.c.m = 2 × 13 × 7 = 182 now, we have to verify tha. Students can solve ncert class 10 maths real numbers mcqs with answers to know their preparation level. 1. the decimal form of 129 225775 is. 2. hcf of 8, 9, 25 is. 3. which of the following is not irrational? 4. the product of a rational and irrational number is. 5. the sum of a rational and irrational number is. 6.
