Question

if the product of two number is 180 and their HCF is 30, find their LCM​

Answer 1

Answer:

6

Step-by-step explanation:

We know that,

HCF(a,b) x LCM(a,b) = a x b

therefore,

$LCM(a,b) =\frac{a*b}{HCF(a,b)}$

HCF = 30

Product = a x b = 180

therefore,

LCM   = $\frac{180}{30}$  = 6

Answer 2

$\blue{\bold{\underline{\underline{\boxed{\star{\mathcal{\textit {Answer: \: lcm \: is \: 6 }}}}}}}} \: \\ \pink{\bold{\underline{\underline{Step - by - step \: Explanation: }}}} \:$

$\orange{hcf \: \times lcm = first \: no. \times second \: no.}$

$⟹30 \times lcm = 180 \\ ⟹lcm = \frac{180}{30} \\ ⟹lcm = 6$

$⟹\boxed{ \blue{lcm = 6}} \:$
