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

l.c.m×h.c.f= product of the 2 numbers

hence

6×a=2×60

hence

a=20

Please mark me as brainliest.

Answer 2

HCF(6,a) = 2

LCM(6,a)= 60 so common HCF and LCM is 6,a

6×a= 2×60

a= 20 .done!!
