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

Apply this formula for all numbers.

Step1:

LCM(664, 643) = 426952

GCD(664, 643) = ( 664 x 643 ) / 426952

= 664 / 643

= 664

Step2:

LCM(1, 79) = 79

GCD(1, 79) = ( 1 x 79 ) / 79

= 1 / 79

= 1

So, Greatest Common Divisor of 664, 643, 79 is 1
