Question

The hcf of two number is 18 and their product is 12960 find their lcm

Answer 1

HI there !!

HCF x LCM = Product of two numbers

18 x LCM = 12960

LCM = 12960 / 18
= 720 =>Answer

Answer 2

Answer:

$LCM \: of \: two \: numbers =720$

Step-by-step explanation:

$\boxed {HCF(a,b)\times LCM(a,b) \\= a \times b}$

$Here , \:it \: is \: given \: that\\</p><p>Product\: of \: two \: numbers =12960$

$HCF\: of \: two\: numbers = 18\\LCM\: of \: two \: numbers = ?$

$LCM =\frac{Product\: of \: numbers }{HCF}$

= $\frac{12960}{18}$

= $720$

Therefore,

$LCM \: of \: two \: numbers =720$
