Given numbers are 428, 242, 118, 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, 242) = 51788

GCD(428, 242) = ( 428 x 242 ) / 51788

= 428 / 242

= 428

Step2:

LCM(2, 118) = 118

GCD(2, 118) = ( 2 x 118 ) / 118

= 2 / 118

= 2

Step3:

LCM(2, 195) = 390

GCD(2, 195) = ( 2 x 195 ) / 390

= 2 / 195

= 2

So, Greatest Common Divisor of 428, 242, 118, 195 is 1
