Given numbers are 771, 306, 212, 428

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

Apply this formula for all numbers.

Step1:

LCM(771, 306) = 78642

GCD(771, 306) = ( 771 x 306 ) / 78642

= 771 / 306

= 771

Step2:

LCM(3, 212) = 636

GCD(3, 212) = ( 3 x 212 ) / 636

= 3 / 212

= 3

Step3:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

So, Greatest Common Divisor of 771, 306, 212, 428 is 1
