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

Apply this formula for all numbers.

Step1:

LCM(788, 128) = 25216

GCD(788, 128) = ( 788 x 128 ) / 25216

= 788 / 128

= 788

Step2:

LCM(4, 385) = 1540

GCD(4, 385) = ( 4 x 385 ) / 1540

= 4 / 385

= 4

Step3:

LCM(1, 549) = 549

GCD(1, 549) = ( 1 x 549 ) / 549

= 1 / 549

= 1

So, Greatest Common Divisor of 788, 128, 385, 549 is 1
