Question

find LCM and HCF of 19 13 and 7 using prime factorisation method​

Answer 1

Answer:

lcm=1729,HCF=1

Explanation:

There is only one common factor is 1 ,so we have multiple

all the numbers to get LCM

19*13*7=1729

if 1 is common factor of all the numbers then we get HCF=1

Answer 2

Answer:

LCM is 1729

HCF is 1

Explanation:

19 = 19× 1

13 = 13× 1

7 = 7 × 1

HCF of 19, 13 and 7 is 1

LCM of 19, 13 and 7 is 1729
