Question

The product of two numbers is 280 and the HCF is 2 the what is the LCM

Answer 1

Step-by-step explanation:

Let the other number be

′

x

′

Given:LCM+HCF=600

⇒14HCF+HCF=600

⇒15HCF=600

⇒HCF=40

⇒LCM=14×40=560

Since HCFxLCM=Product of 2 numbers

=>40×560 = 280×x

⇒x=

280

40×560

⇒x=40×2

⇒x=80

hence the other number is 80.
