Question

Lcm (a, b)=102
find the value of hcf (a, d)

Answer 1

Given: lcm (a, b) = 102

To find: hcf (a, b)

Solution:

• We must know the relation,
• lcm × hcf = product of the two numbers

• Here the numbers are a and b and their lcm is 102. Putting the values in the above relation, we get
• 102 × hcf = a × b
• or, hcf = ab / 102

Answer: hcf (a, b) = ab/102
