Question

find the hcf and lcm of 60,84and108 by using prime factorisation method​

Answer 1

Answer:

60 = 2×2×3×5

84 = 2×2×3×7

108 = 2×2×3×3×3

HCF = 2×2×3 = 12

Answer 2

Answer:

Hey mate here is ur answer↓↑

Step-by-step explanation:

We used the Prime factorisation to find the Hcf & Lcm of 60,84&108

FOR HCF

We took any 2 Numbers between 60,84&108 and divided it..

As a Result we got the hcf of the two numbers--as in attachment i took between 84&60 you can take 84&108/60&108,You will get Hcf then divide the HCF found between those 2 numbers by the number left--as in attachment i got HCF 12 and i divided 108 by 12=>i Got hcf of all those numbers as 12.

For LCM,

WE Took all the Above Numbers and using Prime Factorization,

Found LCM✓
