Question

find the LCM and HCF of the following integers by the applying the prime factorization method 26and 91

Answer 1

26=2×13
91=7×13
HCF=13
LCM=14×13=182

Answer 2

To get the Least Common Multiple (LCM) of 26 and 91 we need to factor each value first and then we choose all the factors which appear in any column and multiply them:

26: 2 13
91: 7 13
LCM: 2 7 13
The Least Common Multiple (LCM) is: 2 x 7 x 13 = 182.



write given numbers 26 and 91 as product of prime numbers

26 = 2 × 13

91 = 7 × 13

common prime factors = 13

HCF = product of common prime factors = 13.
