Question

IF HCF [6, a] =
2 and LCM (6, a) =60 then find a​

Answer 1

Answer:

Since, LCM×HCF=product of two numbers

60×2=6×a

120=6a

6a=120

a=120/6=20

Hope, it help u

Answer 2

Answer:

We know,

HCF of 2 numbers x LCM of same 2 numbers product of the two numbers

Given that the 2 numbers are 6 and a

HCF of the 2 numbers = 2

LCM of the 2 numbers = 60

Hence, according to the formula

HCF of 2 numbers x LCM of same 2 numbers = product of the two numbers. =

2 x 60 = 6 x a

2 x 60/6

= 120/6

= a 20
