Let, the number be 7x and 8x. Then, there HCF would be x.
Since, HCF × LCM=7x × 8x.
=>280x=56x2.
=>x=5.
Since, HCF × LCM=7x × 8x.
=>280x=56x2.
=>x=5.

Let the numbers be 7x and 8x.
∴HCF= x
LCM x HCF = Product of numbers
7x×8x=280
x=280/56=5
∴ Numbers are (7×5)=35,(8×5)=40.
∴HCF= x
LCM x HCF = Product of numbers
7x×8x=280
x=280/56=5
∴ Numbers are (7×5)=35,(8×5)=40.
