Given numbers are 138, 693, 395, 311

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

Apply this formula for all numbers.

Step1:

LCM(138, 693) = 31878

GCD(138, 693) = ( 138 x 693 ) / 31878

= 138 / 693

= 138

Step2:

LCM(3, 395) = 1185

GCD(3, 395) = ( 3 x 395 ) / 1185

= 3 / 395

= 3

Step3:

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

= 1 / 311

= 1

So, Greatest Common Divisor of 138, 693, 395, 311 is 1
