Question

5. Find the HCF and LCM of 60 and 72 using prime factorisation​

Answer 1

Answer:

Prime factorization of 60 and 72 is (2 × 2 × 3 × 5) = 22 × 31 × 51 and (2 × 2 × 2 × 3 × 3) = 23 × 32 respectively. LCM of 60 and 72 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 23 × 32 × 51 = 360. Hence, the LCM of 60 and 72 by prime factorization is 360.

Answer 2

Answer:

HCF=6 LCM=720

Step-by-step explanation:

2  / 60  72

2  / 30  36

2  / 15   18

3  / 5     6

5  / 1      6

2  / 1      3

3  /  1     1

2x2x2x2 x3x3 x5

16 x 9 x 5 = 720

thats what I understand !!!
