Question

If HCF of (6,a)=2 and LCM (6,a)=16 then find 'a'.

Answer 1

as we know that product of two numbers = product of hcf * lcm.............. 36 a sq = 16.*2
36 a sq = 32
a. sq = 32/36 = 8/9
a = √8/9
a = 2/3

Answer 2

Heya!

LCM × HCF = Product of two numbers.

$16 \times 2 = 6 \times a$

$\frac{16 \times 2}{6} = a$

$\frac{16}{3} = a$

Thanks!
