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

Apply this formula for all numbers.

Step1:

LCM(387, 378) = 16254

GCD(387, 378) = ( 387 x 378 ) / 16254

= 387 / 378

= 387

Step2:

LCM(9, 246) = 738

GCD(9, 246) = ( 9 x 246 ) / 738

= 9 / 246

= 9

Step3:

LCM(3, 771) = 771

GCD(3, 771) = ( 3 x 771 ) / 771

= 3 / 771

= 3

So, Greatest Common Divisor of 387, 378, 246, 771 is 3
