Answer 1

Question - 18

Solution

Given 3 numbers - 35 , 49 and 25 . We have to find HCF and LCM of these Numbers

i)HCF

Let us Prime Factorize the given numbers

25 = 5 ×5

35 = 5×7

49 = 7 × 7

∵ There is no comman factor in the primefactorization of 35 , 49 and 25 ;

HCF = 1

ii) LCM

Let us Prime Factorize the given numbers

25 = 5 ×5

35 = 5×7

49 = 7 × 7

∴ LCM of 25,35,49 = 5 × 5 × 7 × 7

LCM of 25,35,49 = 1225
