Question

Given that the lcm of two numbers is 32and their product is 128 determine their HCF

Answer 1

Solution :

______________________

If a ,b are two numbers and

their LCM = l and HCF = h then

a × b = l × h
_______________________

Here ,

l = 32 ,

a × b = 128,

h = ?

h × l = a × b

=> h = ( a × b )/l

=> h = 128/32

=> h = 4

Therefore ,

HCF = h = 4
