Question

the product of two numbers is 1820. if their lcm is 910.then find their hcf.​

Answer 1

$Let \: 'a' \:and \:'b' \: are \: two \: numbers$

$given \: ab = 1820 \: their \: LCM (a,b)= 910 ,$

$HCF (a,b) = ?$

/* we know that, */

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

$\implies HCF(a,b)\times 910 = 1820$

$\implies HCF(a,b)= \frac{1820}{910}$

$\implies HCF(a,b)= 2$

Therefore.,

$\red{ Required\:HCF} \green { = 2 }$

Answer 2

Answer:

ab =1820

HCF * LCM=ab

HCF*910 =1820

HCF=1820-910

HCF= 910
