### Finding GCD of 657, 171, 765 using LCM Formula

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(657, 171) = 12483

GCD(657, 171) = ( 657 x 171 ) / 12483

GCD(657, 171) = 112347 / 12483

GCD(657, 171) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 765

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(9, 765) = 765

GCD(9, 765) = ( 9 x 765 ) / 765

GCD(9, 765) = 6885 / 765

GCD(9, 765) = 9

GCD of 657, 171, 765 is 9
