find the HCF and the LCM of the number 154,198 and 286
Answers
Answer:
Prime factorisation of 154 = 2 × 7 × 11 Prime Factorisation of 198 = 2 × 3 × 3 × 11 Prime factorisation of 286 = 2 × 11 × 13 To find HCF Product of common factors of 154, 198 and 286 = 2 × 11 = 22 HCF (154, 198, 286) = 22 To find LCM Product of common factors of atleast two numbers = 2 × 11 = 22 Product of other factors = 7 × 3 × 3 × 13 = 819 LCM (154, 198, 286) = Product of common factors × Product of other factors = 22 × 819 = 18,018 LCM (154, 198,286) = 18,018 Read more on Sarthaks.com - https://www.sarthaks.com/1020068/find-the-hcf-and-the-lcm-of-the-numbers-154-198-and-286

Answer:
LCM - 18018
HCF - 22
Step-by-step explanation:
Prime factorisation of 154 = 2 × 7 × 11 Prime Factorisation of 198 = 2 × 3 × 3 × 11
Prime factorisation of 286 = 2 × 11 × 13
HCF = Product of common factors of 154, 198 and 286 = 2 × 11 = 22 HCF (154, 198, 286) = 22
LCM- Product of common factors of at least two numbers = 2 × 11 = 22 Product of other factors = 7 × 3 × 3 × 13 = 819 LCM (154, 198, 286) = Product of common factors × Product of other factors = 22 × 819 = 18,018 LCM (154, 198,286) = 18018
