GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(247, 664) = 164008

GCD(247, 664) = ( 247 x 664 ) / 164008

= 247 / 664

= 247

Step2:

LCM(1, 791) = 791

GCD(1, 791) = ( 1 x 791 ) / 791

= 1 / 791

= 1

So, Greatest Common Divisor of 247, 664, 791 is 1
