Given numbers are 789, 633, 388, 155

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

Apply this formula for all numbers.

Step1:

LCM(789, 633) = 166479

GCD(789, 633) = ( 789 x 633 ) / 166479

= 789 / 633

= 789

Step2:

LCM(3, 388) = 1164

GCD(3, 388) = ( 3 x 388 ) / 1164

= 3 / 388

= 3

Step3:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

So, Greatest Common Divisor of 789, 633, 388, 155 is 1
