Question

find lcm and hcf 4/5 and 3/7​

Answer 1

Heya !!

Here is your Answer.

Given :

4/5, 3/10 and 7/15.

Let us first find the LCM..

LCM of Fractions

= LCM(Numerator)/HCF(Denominator)

and,

HCF of Fractions

= HCF(Numerators)/LCM(Denominators)

Using above idea...

LCM (4/5, 3/10, 7/15)

= LCM(4, 3, 7)/HCF(5, 10, 15)

= 84/5

HCF (4/5, 3/10, 7/15)

= HCF(4, 3, 7)/LCM(5, 10, 15)

= 1/30

Hope It Helps
