Question

the h c f of two numbers is 5 and their l c m is 60 if one number is 15 find the other​

Answer 1

GIVEN :

HCF = 5, LCM = 60 and One number is 15.

FIND :

We have to find the other number.

SOLUTION :

• Let other number be M.

We know that..

$\star{ \bold{ \boxed{Product\:of\:two\:numbers\: = \: LCM\:\times\:HCF}}}$

Product of two zeros = One number × Other number.

So,

One number × Other number = LCM × HCF _______ (eq 1)

Put the known values in (eq 1)

=> 15 × M = 60 × 5

=> 15M = 300

=> M = 20

☆ VERIFICATION :

From above calculations we have M = 20

Put value of M in (eq 1)

=> 15 × 20 = 60 × 5

=> 300 = 300

L.H.S. = R.H.S.
