Given numbers are 387, 309, 193, 637

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

Apply this formula for all numbers.

Step1:

LCM(387, 309) = 39861

GCD(387, 309) = ( 387 x 309 ) / 39861

= 387 / 309

= 387

Step2:

LCM(3, 193) = 579

GCD(3, 193) = ( 3 x 193 ) / 579

= 3 / 193

= 3

Step3:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

So, Greatest Common Divisor of 387, 309, 193, 637 is 1
