The LCM of two numbers is 520 and their HCF is 4. If one of the number is 52, then the other number is :
The LCM of two numbers is 520 and their HCF is 4. If one of the number is 52, then the other number is :
[A]40
[B]42
[C]50
[D]52
40
∵ First Number $latex \times$ Second Number = HCF $latex \times$ LCM
=> 52 $latex \times$ Second Number = 4 $latex \times$ 520
$latex => Second\ Number\ = \frac{4\times 520}{52} = 40&s=1$
Hence option [A] is correct answer.
