Question

if lcm and hcf of a,b are 360 and 3 and one number is 12.find a​

Answer 1

$\huge\mathtt\pink{ANSWER}$

90

Step-by-step explanation:

verification of LCM and HCF => LCM × HCF = a ×b

let the unknown number be ‘a’

=> 360×3 = 12× a

= 1080 = 12a

So, a = 1080/12

therefore a = 90

So, the value of a = 90

verification

360 × 3 = 90 × 12

1080 = 1080

therefore LCM = HCF
