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

Apply this formula for all numbers.

Step1:

LCM(660, 354) = 38940

GCD(660, 354) = ( 660 x 354 ) / 38940

= 660 / 354

= 660

Step2:

LCM(6, 388) = 1164

GCD(6, 388) = ( 6 x 388 ) / 1164

= 6 / 388

= 6

Step3:

LCM(2, 636) = 636

GCD(2, 636) = ( 2 x 636 ) / 636

= 2 / 636

= 2

So, Greatest Common Divisor of 660, 354, 388, 636 is 2
