Question

find the hcf and lcm of 50 and 60 in prime factorisation

Answer 1

LCM of 50 and 60 =
The prime factorization of 50 is: 2 x 5 x 5 and that of 60 is: 2 x 2 x 3 x 5
Eliminate the duplicate factors of the two lists, then multiply them once with the remaining factors of the lists to get LCM which is equal to 300.


The prime factorization of 50 is: 2 x 5 x 5 and that of 60 is: 2 x 2 x 3 x 5
So.HCF = 2*5 = 10

Answer 2

After prime factorisation, we get to know

50 = 2 × 5 × 5

60 = 2 × 2 × 3 × 5

LCM = 2 × 2 × 3 × 5 × 5 = 300

HCF = 2 × 5 = 10
