Given numbers are 428, 396, 851, 195

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

Apply this formula for all numbers.

Step1:

LCM(428, 396) = 42372

GCD(428, 396) = ( 428 x 396 ) / 42372

= 428 / 396

= 428

Step2:

LCM(4, 851) = 3404

GCD(4, 851) = ( 4 x 851 ) / 3404

= 4 / 851

= 4

Step3:

LCM(1, 195) = 195

GCD(1, 195) = ( 1 x 195 ) / 195

= 1 / 195

= 1

So, Greatest Common Divisor of 428, 396, 851, 195 is 1
