Question

If lcm of a and 18 is 36 and the hcf of a and 18 is 2,find the value of a

Answer 1

Answer:

$\red {Value \:of \: a } \green {=4}$

Step-by-step explanation:

$Given \: two \: numbers \: are \: \blue {a} \\and \: \orange {36}$

$HCF(a,18) = 2\:and\\LCM(a,18) = 36$

$\boxed { \pink {product \:of \: two \: numbers = product \:of \: their \:LCM \:and \:HCF }}$

$\implies a \times 18 = 36\times 2$

$\implies a = \frac{36\times 2}{18}$

$\implies a = 4$

Therefore.,

$\red {Value \:of \: a } \green {=4}$
