Question

.If HCF (6, a) = 2 and LCM (6, a) = 60, then find a.

Answer 1

Answer:

a=20

Step-by-step explanation:

We know that

a×b=HCF(a,b)×LCM(a,b)

Given b=6, HCF(6,a)=2,LCM(6,a)=60

Therefore

a×6=2×60

a=120/6=20

Therefore the value of a=20.

Answer 2

Answer:

20

Step-by-step explanation:

HCF(a,b)×LCM(a,b)= a×b

HCF(6,a)×LCM(6,a)=6×a

2×60=6×a

120=6×a

a=20
