Question

if HCF ( a, 42 )= 2 , LCM ( a, 42 ) = 546 then find 'a'
​

Answer 1

Answer:

a,42×a,42=546

a²=546/42×42

you'll get your answer

Answer 2

HCF (a,42) = 2

LCM (a,42) = 546

As we know,

LCM×HCF = Ist No. × 2nd No.

2×546 = a×42

2×546/42 = a

a = 26

Hope this helps you

Have a great day!!
