Question

11 if a is the hcf of 546, 294 and 3066 and b is lcm of 42, 14 and 21, what is the relationship between a and b?

Answer 1

hcf x lcm = product of numbers

Answer 2

We know that,
LCM * HCF = product of two numbers
given that,
a and b are the HCF and LCM of the given numbers respectively,
So therefore,
LCM * HCF = ab
